(2.3.1) Popover data attributes ignored when using selector option

Created by: neilgoodman

This is a dup of #7086 (closed), but it is still an issue for 2.3.1. Here is a jsfiddle repo:

I did make a pull-request (#7094) to solve this issue for 2.3.0 (which worked and passed tests).

I think the issue now is that the fix in 2.3.1 is located in the enter method of bootstrap-tooltip, but this method doesn't get fired for bootstrap-popover because the trigger defaults to click and not hover:

I am hacking in my fix on the 2.3.1 code for now in my projects.
