tests: use test compositor in queue-test

Most of the code of the queue-test is covered by the test compositor,
so we can save few lines and use the test compositor instead.
I think it's also more readable.

This patch removes timeout from the test. We plan to add timeout
to all tests later, though.

v2.
  rebased to master
