qunit: Update tests to not assume animations use setTimeout

As of jQuery 1.12, animations use requestAnimationFrame in modern
browsers, which cannot be forced to finish synchronously by merely
mocking the 'setTimeout' and 'Date' clocks via Sinon.

For jquery.color, reduce duration from 10ms to 3ms (not 10ms which will
now be real time, not 0ms since we do want to test real frames).
