Failing test cases for #3434

Not obvious why the tests havn't run.

Seems like Travis might be having some issues.

Wonder if there's anything we can do to make travis run this. Not showing up since yesterday. Close this and open a new PR?

Adding a new commit should do

Rebased and pushed again, seems like Travis is running now.

Taking a look at this. First thing that came to mine was doing something like the following in ListSerializer:

    @property
    def errors(self):
        ret = super(ListSerializer, self).errors

        if ret == {}:
            return ReturnList([], serializer=self)

        if isinstance(ret, dict):
            return ReturnDict(ret, serializer=self)

        return ReturnList(ret, serializer=self)

    @property
    def validated_data(self):
        validated_data = super(ListSerializer, self).validated_data

        if validated_data == {}:
            return ReturnList([], serializer=self)

        return validated_data

All tests pass including these.
