[nautilus/gnome-3-6] slot: rework query editor visible state synchronization

[Cosimo Cecchi <cosimoc src gnome org>]

commit bde82c2791a2fa7bac2f2384b033bebb4d9710a9

    slot: rework query editor visible state synchronization
    
    Fix a case where entering a directory from the search results would not
    take the query editor down, and refactor some code around the state
    synchronization between the two objects.
