Philip Withnall 511c5f5bf0 tests: Wait for gdbus-testserver to die when killing it 
This was previously done (by commit 63038d1e4c) in one of the cases
where `kill_test_service()` was called — but not the other.

This meant that one instance of `gdbus-testserver` could still be
around when (as it happens, due to the order of the tests) the
`/gdbus/proxy/no-match-rule` test was run. It would start a second
instance of `gdbus-testserver`, which would exit early due to the test
name still being owned on the bus. The first (killed) instance of
`gdbus-testserver` would then exit, leaving no test servers running, and
hence the new test would fail.

This was being seen as frequent CI failures, particularly on FreeBSD
(must have slightly different timing for process signalling and
termination from Linux).
