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:

    https://foss.heptapod.net/mercurial/mercurial-devel/-/jobs/552404

  $ hg init repo
  $ cd repo

  $ touch foo
  $ hg ci -Am 'add foo'
  adding foo

  $ hg up -C null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

this should be stored as a delta against rev 0

  $ echo foo bar baz > foo
  $ hg ci -Am 'add foo again'
  adding foo
  created new head

  $ hg debugindex foo
     rev linkrev nodeid       p1           p2
       0       0 b80de5d13875 000000000000 000000000000
       1       1 0376abec49b8 000000000000 000000000000

  $ cd ..
