1. Do a POST /RemoteTest
2. Do a POST on /RemoteTest/{id}/ModelA
   Get rid of handler creation for each request. #2 Should result in a field being injected into the JSON in the beforeRemote but it isn’t. (edited)

In the test case I sent, in RemoteTest.js, if you change RemoteTest.beforeRemote('prototype.__create__ModelA', … ) to RemoteTest.beforeRemote('create', … ) you can see it works for non-prototyped relationships
