tests: Verify SD TX callback processing after P2P find is stopped

These are far from perfect since timing is quite difficult to match for
the case that behaved incorrectly. Anyway, it looks loke
p2p_service_discovery_peer_not_listening was able to hit the error now
and then, so this should be sufficient as a regression test case.
