Animation tests: Fix flaky transition-and-animation tests

transition-and-animation-2.html was changed earlier to not rely on
accurate setTimeout callback timing, by waiting for an animation end
event instead.

transition-and-animation-1.html and transition-and-animation-3.html
are now fixed in the same way.
