fix(tooltip): tooltips will hide on scope.$destroy

Josh David Miller · Josh David Miller · commit 3e5a58e54cda · 2013-05-09T09:24:10.000-07:00
When an element on which the tooltip is applied is destroyed (along with its scope), the tooltip popup will now be closed if it was open. Also refactored the $locationChangeSuccess binding as well to not waste a run of `hide()` unless the tooltip was already open, following the same pattern used in this bug fix. Closes #410.
