This pull request addresses

The issue arises from mutedByOthersChanged in selfUtils. This function should not trigger a user mute update when the user receives a notification from the server that the server has been updated remotely to a muted state but not from another person.

by making the following changes

I have added the fix to mutedByOthersChanged that will avoid updating the mute state when the server state doesn't change by others and added testcases for selfUtils.mutedByOthersChanged
