Title: fix(tooltip): animation causes tooltip to hide on show

Add logic to handle cases where hide/show can be called multiple times
even before their timeouts complete.

This is more ugly logic to handle degenerate cases. Hopefully switching
over to ngAnimate and cleaning up the logic of tooltips will be better.

Fixes #1847
