Must hide tooltips before re-rendering or they'll persist after eleme…

…nts removed from DOM.

refs #2864

The issue with tooltips persisting on line item form is caused by the original tooltip element being removed from the DOM when the templates re-rendered after clicking an action. The recommended workaround for this is to first hide your tooltip before removing the elements from the DOM: twbs/bootstrap#2298

I haven't browsed around looking for this issue in other spots, but it wouldn't surprise me if there are other instances of this to fix. Would like to get feedback on this solution before checking for other places to fix.

Hey Jeff! Great to have you back.
Thanks for the fix.

We should use the .tooltip('destroy') method instead. Otherwise all events will still be bound in memory.

See twbs/bootstrap#3880

@tvdeyen Thanks. I get an error trying to use destroy it looks like it was renamed dispose at some point, but that appears to work as intended for unbinding events.

I also noticed this is happening all over the place so going to make a pass through the admin to see where else needs to be fixed before this is merged.

Could this be related to #2421 ?

[JDutil]

@kennyadsl yea it looks like it. I'll probably close this in favor of fixing in that file so solution works everywhere, but my initial attempts don't seem to work.

Closed in favor of #2890
