Adrian Torres 1daf8eb127 [FIX] *: set ondelete policy of required Selection fields 
With this commit, Selection fields with `required=True` which are
extended via `selection_add` are given proper ondelete policies to
ensure the cleanup of records containing these extended options during
uninstall of the extending module.

This commit also cleans up leftover uninstall hooks that were being used
to handle the same set of problems prior to the ondelete mechanism being
implemented for Selection fields.
