[BUG]`fetch_links=True` doesn't work with `View`s

[efrechette-rga]

Using fetch_links=True with a View results in an error:

    document = yield from self._find_one().__await__()  # type: ignore

AttributeError: _database_major_version

To Reproduce

class MyView(View):
    some_field: str
    some_link: Link[MyOtherModel]

    class Settings:
        source = MyModel
        pipeline = ...

MyView.find_one(MyView.some_field == "hi", fetch_links=True)

Expected behavior View.find_one(..., fetch_links=True) works exactly like it does for Documents.

+1 fetch_links=True does not fully populate the linked documents but Object { id: "668ea3dda0a3e171ae3fbd71", collection: "users" } in the linked field of the linking document.
