    clutter: Set slave=master in IM forwarded key events
    
    The fix is twofold. On one hand, it makes sense not to relate IM (nor
    any other) generated events to a HW device. On the other hand, if we
    are unfortunate that an IM event is in flight when we are switching
    to another TTY, it may arrive at a time when the source device is no
    longer existent.
