Title: Cleaned up a bad check inside of `Ember.View._hasEquivalentView`

Previously, there was a bad check that was causing routes with the same template and controller, but **different** view classes, not to render.

I believe the original author of this function had intended to preform this check, but accidentally used `prototype` instead of `constructor`. However, since these are view instances, not view classes, checking `prototype` is invalid.
