    file chooser: Avoid nonworking search+save combinations
    
    With the location entry up in the header bar in save mode, we can
    end up with the search model being in use when the user types in
    the location entry. In this case, we don't make the Save button
    sensitive as we should.
    
    Having two entries in the dialog is somewhat confusing anyway,
    so just stop the search when the user starts typing in the location
    entry.
