WPB-15476 [iOS] Crash on persistentStore first

Issue

While removing a user from a team a crash occurs while we delete the Account. We receive two events one is a teamMembershipLeave event and the other is a UpdateConverationMemberLeave.

We don't wait for the deleteAccount method to be finished before processing the second event. Then when processing UpdateConverationMemberLeave event, there is a context.saveOrRollback() which will fail because we already removed the persistentStore.

This PR also removes a retain cycle in ProfileHeaderViewController.

Testing

1. create personal user
2. invite to team A
3. remove from team A

App should not crash
