[gtk+/gtk-3-18] file chooser: Avoid search interruption

    file chooser: Avoid search interruption
    
    When the search entry is shown, the 'special' nature of
    ., ~ and / should not trigger the location entry, because
    that interrupts the search and is likely not what the
    user intended.
