[easytag] Check if the full commandline path is hidden

[David King <davidk src gnome org>]

commit c726854e1a7baad9356a0022378d63629f3b8866

    Check if the full commandline path is hidden
    
    The last element of the commandline path was skipped when checking for
    hidden paths, so rearrange the check so that all elements of the path
    are tested.
