Remove instanceof Ember.View check.
Remove instanceof Ember.View check.

In Ember 1.13+ Ember.View is a different deprecated class than the
parent class of `Ember.Component`, so checking for `t instanceof
Ember.View` when `t` was a component would not return true.

I discovered this while updating ember-modal-dialog to Ember 1.13.

This issue blocks updating that lib.
