[orca] Return early when generating status bar items for itemless status bars

commit 1c4b86617cf07fd9932bfbb4cfd5674449e05c2e

    Return early when generating status bar items for itemless status bars
    
    The status bar in Gedit, and now Pluma, are inaccessible -- exposing no
    children. Thus when we get the on-screen items, all we wind up with is
    the status bar. Calling generate for it leads to infinite recursion.
