Subject: [PATCH 2/2] Update tooltip.js

There Should Be one unique event through which user can change message or destroy tooltip from element because in case of $destroy there are many library which are also listening $destroy event. So for resolving our purpose we are introducing another event $uibTooltipdestroy with which user can remove uibtooltip from element without disturbing other library like ui-grid.
