Bugfix: call resolver function in DjangoConnectionField as documented (#1529)

* treat warnings as errors when running the tests

* silence warnings

* bugfix: let DjangoConnectionField call its resolver function

that is, the one specified using DjangoConnectionField(..., resolver=some_func)

* ignore the DeprecationWarning about typing.ByteString in graphql
