Data: use `assign` instead of `merge` here ?

[bartocc]

I might be wrong, but shouldn't we use Ember.assign instead of Ember.merge here to avoid a 3.6 deprecation warning ?

Deprecation warnings are also caused by (in 3.7)
data/addon/-private/system/model/errors.js

errorsFor(attribute) {
    let map = get(this, 'errorsByAttributeName');

    if (!map.has(attribute)) {
      map.set(attribute, new A());
    }

    return map.get(attribute);
  },

Yep, I think both things should be easy to fix and we'd love PR's for them 😸

Looks like https://github.com/emberjs/data/pull/5812 is already open for fixing the Ember.merge deprecation.
