Validation 'required' doesn't work on relationController with hasMany

[jakobfdev]

Expected behavior

When Parent hasMany Child models, it should be possible to set children to be required and when using RelationController to create the parent and the children in one form.

Actual behavior

Upon creation of the parent, some children are created by the user with a deferred binding (I suppose) in the RelationController. When trying to save (children are present in the form), the validation fails and says that children are required.

Reproduce steps

https://github.com/jBOKA/oc-deferredbindingvalidationtest-plugin
Install plugin, try to create parent.

October build

PS: It is also not possible to have the inverse relation set to required, because then even creation of the children fails the validation.
