Player: confine command data resending on permission recalculate to post-spawn only

this fixes crashes when PurePerms causes this to be recalculated on player login - the client doesn't like receiving this before StartGame and crashes.

Confining this to post-spawn should not cause any issues since any permission recalculation in login events will be reflected immediately afterwards when the initial command data is sent anyway.

This same bug popped up at 1.1... I don't know why it wasn't fixed properly back then.

-- **Your pull request will be checked and discussed in due time.** Since the team is scattered all around the world, your PR may not receive any attention for some time.

+- **If a contribution does not meet our standards, changes may be requested or the pull request may be closed.**
-- **Avoid using GitHub Web Editor**. The web editor lacks most useful GIT features and **should only be used for very minor changes**.

-
-- **Do not copy-paste code**. There are potential license issues implicit with copy-pasting, and copy-paste usually indicates a lack of understanding of the actual code. Copy-pasted code is obvious a mile off and **any PR like this is likely to be closed**. If you want to use somebody else's code from a Git repository, **use [GIT's cherry-pick feature](https://git-scm.com/docs/git-cherry-pick)** to cherry-pick the commit. **Cherry-picking is the politer way to copy somebody's changes** and retains all the original accreditation, so there is no need for copy-pasted commits with descriptions like `Some code, thanks @exampleperson`.

+### Pull requests
 - **Create a new branch for each pull request.** Do not create a pull request with commits that exist in another pull request.
-
-- **Code should use the same style as in PocketMine-MP.** See [below](#code-syntax) for an example.
-
-- **The code must be clear** and written in English, comments included.
-
 - **Use descriptive commit titles.** You can see an example [here](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html).
-
+- **Do not include multiple unrelated changes in one commit.** An atomic style for commits is preferred - this means that changes included in a commit should be part of a single distinct change set. See [this link](https://www.freshconsulting.com/atomic-commits/) for more information on atomic commits. See the [documentation on `git add`](https://git-scm.com/docs/git-add) for information on how to isolate local changes for committing.
-- **Try to stick to one change per commit.** This ensures that if you create a PR with several changes, we can decide which ones we wish to include and which ones not to include.
+- **Your pull request will be checked and discussed in due time.** Since the team is scattered all around the world, your PR may not receive any attention for some time.
-
+- **It is inadvisable to create large pull requests with lots of changes** unless this has been discussed with the team beforehand. Large pull requests are difficult to review, and such pull requests may end up being closed. The only exception is when all features in the pull request are related to each other, and share the same core changes.
