It seems that `RxChat.typingUsers` sometimes might not remove the user when receiving `typingStopped`

[SleepySquash]

Summary

A strange bug occurred: in Chats tab there's a user that is displayed in a group like they are typing (the "Name is typing..." is displayed). However, judging by the logs, it seems that we did receive both typingStarted and typingStopped events. So this problem is related to either RxChat.typingUsers or reactivity rebuild of the chat tile?

Steps to reproduce

1. Keep tying to some chat from other account.
2. ???
3. Notice the hang?

What is the current bug behavior?

... is typing hanging.

What is the expected correct behavior?

No ... is typing is hanging.
