    file-operations: Fix regression for unmount empty trash
    
    The new call back empty_trash_prompt_cb as part of ed23b17a50da5d86339cc5930b62814eda1416ff
    leaves off a catch all to do_unmount() which would only be called if
    the user selects "Do not Empty Trash" when unmounting a volume.
    Add a clause to check for GTK_RESPONSE_REJECT with call to do_unmount().
