[meta-issue] Protractor should degrade more gracefully for non-angular pages

[juliemr]

Big issue for collecting ideas and coordinating the large goal - in general, Protractor should be kinder when confronting a page which does not have Angular available.

We'd like to preserve the property that we always override modules when the user requests it.

Better bootstrap-pausing also falls into this category.
