Cleanup 'container lookup is normalized' test

This addresses code discussion in up #2350.
deprecate Ember.Application#initialize

This was never intending to be supported. It was
used to deal with app initialization shortcomings.
Hopefully all of those have now been dealt with.

In situations where default initialization behaviour
is not wanted please use Ember.Application#deferReadiness
and Ember.Application#advanceReadiness.

Insert adjacent child views in batches rather than
individually.

This will, for example, improve the rendering
performance of #each when initially rendering an
unloaded RecordArray.

A common workaround to this issue was to wrap your
#each inside an {{#if isLoaded}}.
