Change subject: res_pjsip_outbound_registration.c: Filter redundant statsd reporting.
......................................................................


res_pjsip_outbound_registration.c: Filter redundant statsd reporting.

Increasing the testsuite shutdown timeout before forcibly killing
Asterisk allowed more events to be sent out.  Some tests failed as
a result.  The tests/channels/pjsip/statsd/registrations failed
because we now get the statsd events that a comment in the test
configuration stated couldn't be intercepted.  Unfortunately, we
get a variable number of events because of internal status state
transition races generating redundant statsd events.

We were reporting redundant statsd PJSIP.registrations.state changes
for internal state changes that equated to the same thing publicly.

* Made update_client_state_status() filter out redundant statsd
updates.

ASTERISK-26527
