* Manually restart the sync only when entering the `error` state

* Use stopSync instead of the roomListService directly on client deinit

* Replace WeakClientProxyWrapper with callback based delegate

* Fix homescreen user avatar not automatically updating

* Replace default Build SDK profile with reldbg, which is fast but also doesn't crash

* Always show the loading indicator when the room list is not in a `running` state

* Implement delayed user indicator presentations through the normal API

* Fix the unit tests

* Replace UserIndicatorController delayedIndicators dictionary with a plain set
