Florian Müllner afcd90ae27 messageTray: Fix _hideTray() being called recursively
_hideTray() is called by _updateState() when the tray is visible
but should be hidden; however, _updateState() may be called again
from within _hideTray() when releasing the GrabHelper grab, so
unless we update the _trayState variable before that, _hideTray()
will be called a second time.
