Method/attribute of same name of return type fail to typecheck

[tharvik]

class A: pass

class B:
    def A(self) -> A: pass

B().A()

is a valid python code, but mypy

/tmp/asd.py: note: In function "A":
/tmp/asd.py:4: error: Invalid type "A"

It was found while typing datetime.datetime.tzinfo which return a tzinfo.

Also found it while simply using it as attribute

class A: pass

class B:
    A = ...  # type: A

B().A

gives

/tmp/asd.py:4: error: Invalid type "A"

Damn, duplicate of #1775, sorry about that.
