run-tests: send the test result after freeing the channel
Sending the message about the test being "done" signals to the main thread that
a new test can be started. Before this changeset, we sent this signal before
freeing the channel, there is room for a race condition where a new test would
search for a channel before the old test freed the one it used.
This is an example of the failure it would produce:
