fix(ngInclude): allow ngInclude to load scripts when jQuery is included

In 1.2, the behavior of ngInclude was modified to use DOM APIs rather than jqLite. This means that
even when jQuery was loaded, ngInclude was not calling into it, and thus scripts were not eval'd
as they had been before. Although the use of ngInclude to eval scripts as a lazy-loading strategy
was never an intentional feature, this patch restores the ability to do so.

Closes angular#3756
