Relationship data for include missing

[blmundie]

I think this might be related to #47. When including posts the relationship data for posts is included, but for posts.users the relationship data for posts is not included. posts,posts.users works

The line direct_children_includes = includes.reject { |key| key.include?('.') } in serializer.rb:267 seems to cause this. Changing it to direct_children_includes = includes.reject { |key| key.split('.')[0] } fixes this. I couldn't tell if this is intended or not, because there is a test that checks for it.

Hmm, that's not intentional. In a pre-1.0 version of the spec, the spec said to only include leaf nodes for includes, but in the 1.0 spec they changed it to include all parent nodes as well. There was a PR that fixed it (#50) and I thought we have good test coverage for making sure that this works correctly. You're definitely using the latest version of this gem? Also, #47 that you referenced was actually caused by him overriding format_name and a bad interaction with strings/symbols—have you overridden format_name?

Yes, I'm definitely using the latest version. It looks to me that the tests on line 705 and 739 test for this.
