When using get with path (eg. get('foo.bar.baz')), get method is called
only on the current object and computed property will be called. Because
there is no easy way to overwrite the computed property, I moved
incomplete record loading to ember-data. It's not DRY and it should be
rewritten, but I don't want to do it at this point as we will need to
completely rewrite it when upgrading ember-data.
While testing in the wild I spotted a few problems with it:
* it didn't work for camel case names.
* it was sometimes setting loaded data too late - it needed to use find
and then save data on the record. Instead it should save data in
special array saved on store, indexed by clientId
* there is already method to get attributes in ember-data, it just
doesn't work with Travis.Foo.get('attributes'), it needs
Ember.get(Travis.Foo, 'attributes') - it makes implementation much
shorter
