Closing animated delayed tooltip breaks on scope destroy

[tak-amboss]

If I append a tooltip with popupdelay to a link on statechange tooltip (mostly) becomes null and the following error is thrown (in Firefox):

Error: tooltip is null $tooltip/link/hide/transitionTimeout
<@angular-ui-bootstrap-tpls-0.7.0.js?v=83adf2556701:2143 timeout/timeoutId
<@angular-1.2.3.js?v=83adf2556701:13363 completeOutstandingRequest@angular-1.2.3.js?v=83adf2556701:4026 Browser/self.defer/timeoutId
<@angular-1.2.3.js?v=83adf2556701:4332

in Chrome:

TypeError: Cannot call method 'remove' of null

Here is a fiddle of this issue:

If I set poupDelay to '0' or animation to 'null' the issue doesn't occur.

Additionally in this fiddle the tooltip isn't even displayed in Firefox; in my local files this isn't a problem.

@tak-aryelle can you reproduce it as well without ui-router?

@pkozlowski-opensource destroying the scope causes the issue as well: http://jsfiddle.net/tak_aryelle/ujRy2/3/

@tak-aryelle thnx for narrowing it down, definitively a bug that should be addressed... Would you be up to preparing a pull request?
