Robert Bragg 175317a754 test-timeline: instantiate a stage so the master clock runs 
This makes test-timeline get the default stage so there is at least one
stage instantiated. Without any stages the master clock will never run
which was causing this test to fail.

/* This test runs three timelines at 30 fps with 10 frames. Some of
the timelines have markers. Once the timelines are run it then
checks that all of the frames were hit, all of the markers were hit
and that the completed signal was fired. The timelines are then run
again but this time with a timeout source that introduces a
delay. This should cause some frames to be skipped. The test is run
again but only the markers and the completed signal is checked
for. */
