Touch related items

[JoanBonnin]

Hi there! I'm facing an issue when creating (not when updating, which works well) a resource with a nested form. The issue comes when the related (nested) resource has a touches (touching parent timestamps) property related to the main and new resource. In a rapid (and probably not so accurate) debug session, I found out a kind of circular dependency that generates an infinite loop preventing the main resource to be actually created.

Thanks and love this project.
