FIX: Cleanup PresenceChannel instances when composer closed (#14741)

Browse Source 
I was previously relying on `this.isDestroying` returning `true` during `willDestroyElement`. This was an incorrect assumption.

This commit refactors the logic into an explicit `cleanup` function, and also adds some cleanup for empty keys in the `subscribedProxy` array
