Better chunking behaviour and add members on PRESENCE_UPDATE.

Browse Source 
This should hopefully cover all cases where members are added.
There was a bug where an array of chunks received would get entirely
processed if only a single chunk was received. This was fixed by
explicitly bailing early if we're requesting for chunks.
