    introspection: Clear idle id when done with it
    
    commit 3c82a664155695bd4243c2a964b3ec22c544f3f6 added
    an idle handler to help process introspection requests
    asynchronously.  It failed to clear the idle handler id
    when the idle finished, however.
    
    This commit fixes that.
