res_pjsip_outbound_registration: Fix reference leak.

Every time a registration started, sip_outbound_registration_response_cb bumps
the ref count on client_state then pushes a handle_registration_response task.
handle_registration_response never unreffed it though.  So every time a
registration goes out, the ref count goes up by one.

This patch adds the unreffs to handle_registration_response.
