; Fix a failure when running server-tests via the command line

* test/lisp/server-tests.el
(server-tests/server-force-stop/keeps-frames): Delete every new frame
created during the test.  On some systems, 'delete-terminal' will
delete the frames for us, so this ensures that if there are no new
frames, nothing happens.
