tests: remove event loop from command test

This effectively reverts

  commit 39c77fe586baccd0a4a9862e8cf7c78ac7af3494
  Author: Michal Prívozník <mprivozn@redhat.com>
  Date:   Wed Jan 16 11:58:00 2013 +0100

    Introduce event loop to commandtest

because nothing in the current test suite needs this
event loop.
