datePickerPopup with custom datepicker-template-url. focus() not working.

[Rouche]

Bug description:

Was working in 1.3.3 (If you change the script link in the plnkr you cann see)
I dont know if this is related to #5998 but i got bug since 2.0.0

Link to minimally-working plunker that reproduces the issue:

Use the date popup called "Test Datepicker alone" it will pop the one using uib template and the one with a custom template. (Both templates are completelly identical)

You will see the "Cannot read property '0' of undefined" line 1725.

Should this go in a setTimeout() if the element is not there?
What boggles me completelly is... both templates are identical and put in cache.

Using templateCache directly did not help either.

Version of Angular, UIBS, and Bootstrap

Angular: 1.5.8

UIBS: 2.1.3

Bootstrap: 3.3.7

jQuery: 3.1.0
