Fix nested include attributes

Browse Source 
When the requests asked for a nested attribute in the `include` and it's
missing or empty, don't break because the type of the object can't be
determined.

If the request is for a collection and none of the elements has the
attribute, it will not be added to the `linked` key, similar to what
happens with simple includes.
