DEV: Refactor presence manager to deal with multiple composer states.
This change amends it so we use a static service to keep track of
the typing presence.

It correct various edge cases the initial implementation had

- Faster close messages
- When composing on topic 1 and viewing topic 2 we had incorrect
  presence
- Changing a running composer to reply as new topic or reply to a
  differet topic would not correctly shift presence
