fix(tooltip): null scope check in isOpen watch

RobJacobs · RobJacobs · commit 1f94104b6993 · 2015-10-23T15:59:05.000-04:00
The watch for the isOpen property from the model was not checking to see if the internal tooltip scope was still valid (null or undefined) before comparing the value to the tooltip scope isOpen property. Closes angular-ui#4697 Fixes angular-ui#4683
