Fix tooltip in angular 1.2.0.

[jimrollenhagen]

Use bind-html-unsafe instead of ng-bind-html-unsafe, as per #813.

@jimrollenhagen thnx for your PR but this was already addressed in 7589339. Arguably it is not the best approach but what you are proposing would force people to include the ngSanitize module and as such it should be documented, demo site updated etc.

Based on the above reasons I'm going to close this PR but I'm happy to discuss this in more details.

@pkozlowski-opensource I think you may have read my PR wrong?

In 7589339 you added the ui.bootstrap.bindHtml dependency to the tooltip module, but never used it. The typeahead template was changed to bind-html-unsafe but the tooltip was not updated.

My commit simply addresses this issue.
