res_pjsip: Fix SEGV on pending-qualify contacts

Browse Source 
Permanent contacts that hadn't been qualified yet were missing
their contact_status entries causing SEGVs when running CLI
commands.

This patch makes sure that contact_statuses are created for
both dynamic and permanent contacts when they are created.
It also adds checks in the CLI code to make sure there's a
contact_status, just in case.
