Fix crash when hinting with angular.js.

Updated to a version of tern that fixes the bug.
Take out the excludes of minified libraries, as they all work now that the bug is fixed.
Stil exclude require and jquery files since we have json defs files for those that have better type information.
Fixes Issue #3827

Fix a bug where the hinter was not failing over to gueses. Added code to Session.getHints to detect when guesses are needed so the caller can get the guesses from tern and call getHints again.
