Force the room list items to update their height when the compactRoomList setting is changed.

Force the room list items to update their height when the compactRoomList setting is changed.

The solution is a bit janky but for whatever reason the height wasn't updating properly which seems to be a qml bug, it sometime happened slow, sometime you would have to turn NeoChat off then on again.
