[commands] Restart the StringView properly in Context.reinvoke.

Browse Source 
The old code for some reason assumed that the length of the command
would be 1. This is because when I tested this I would use single
letter command names and it would "just work" when in reality it was
completely incorrect.

A reminder to thoroughly test instead of just fitting something to work
