[orca] Only treat list items as widgets if they are not inside a list parent

[Joanmarie Diggs <joanied src gnome org>]

commit 97cbd3ee401b8722c1aa46bb6eded081b33d83d8

    Only treat list items as widgets if they are not inside a list parent
    
    We used to do other things rather than check the parent role because user
    agents were mistakenly using the list role for listbox as well as for list.
    This fixes our treating editable list items as widgets rather than text.
