Fix key remapping for embedded belongsTo

[ef4]

Closes #4068. This implements the same semantics for key that are used in JSONSerializer.

Does the same change need to happen in _serializeEmbeddedHasMany as well?

[bmac]

Also @ef4 do you mind amending the commit message to start with [BUGFIX beta]?

@ef4 @bmac: I would think yes.. it needs to be included in _serializeEmbeddedHasMany as well... i primarily use embedded hasMany and that is the area in which i am having the issue.

[ef4]

I fixed hasMany too, and amended the commit message.

Thanks @ef4

@bmac @ef4 thanks for the effort to fix this!

Quick question: since this thing is now merged.. that meant the fix will be available in the next release? or can i just reinstall my ember data and the fix will be there?

@grapho This will be in the next release. Otherwise, you can pin to the commit in package.json if you are using ember-cli post Ember Data 2.3.0, or #canary in bower.json

thanks @fivetanley!
