Partially fix include directive specs

This code is somewhat copied from this branch:
https://github.com/crunchybananas/jsonapi-authorization/tree/v0_10

The specs for included resources pass using questionable assertions.
It seems that the new code has a bug and the assertions shouldn't need
to be changed here.
