Fix room topic change tooltip
There are usersA and userB. They are in the same room.
userA changes topic to "test"
userB Spark is showing message in room: userA has changed the subject to: test
userB Spark tooltip displays such message: /me has changed the subject to: test
tooltip shoud show the same as message in the room
Closing this as it was tested only against Exodus and Spark behaves a bit different and i have created two new tickets instead of this one.
