    MessageTray: fix popping up after there were modals
    
    Open a modal dialog, try to open the message tray -> no effect, the message
    tray is blocked by the dialog.
    Close the dialog, try to open the message tray by pointer -> still
    no effect, because the old timeout id was not cleared the first time,
    so the dwell callback thinks the tray is about to open.
