    app: fix backup creation on crash.
    
    The call to "gimp-xcf-save" was not updated to the new API using a
    drawable array and a GFile.
    Also for the drawable array, do not actually create it as anyway this is
    a dummy argument (so far XCF saving does not even look at this argument
    and just re-check the selected drawables).
