Destroy the generic_monitors container after the core_instances in ccss

For each item in core_instances disposed of in the shutdown of ccss, any
generic monitor instances referenced by the objects will be removed from
generic_monitors during their destruction.  Hilarity ensues if
generic_monitors no longer exists.

Thanks to the Asterisk Test Suite's generic_ccss test for complaining loudly
when it ran into this.
