fix(mdTooltip): fix regression that broke tooltips on Firefox

Remove check for pointer-events not equal to none to resolve non-visible tooltips on Firefox.
Add Chrome & Firefox as default test runners in karma task to avoid regressions like this in the future.
Improve and automate use of ngAnimateMock

Fixes #3047. Fixes #3250.  Fixes #3430. Closes #3467.
