Simon McVittie 3d50691a30 g_test_dbus_down: Ensure next test does not use old connection
There's a race condition somewhere in GTestDBus that can result in
the next test being started at a time when g_bus_get() would still
return the connection that is in the process of closing. This can
be reproduced reasonably reliably by running the gapplication test
10K times in a loop.

Instead of relying on waiting for the weak reference to be released,
we can force the issue by clearing it.
