mypy_extensions.TypedDict errors because when creating a class, it is inferred as an instance

[libre-man]

Steps to reproduce

1. Create a new variable Dict1 = mypy_extensions.TypedDict('Dict1', {'a' : int}).
2. Create a class class Dict2(Dict1, Total=True): pass
3. Run pyling

Current behavior

Pylint gives an error for the class creation as inheriting from a non class is invalid.

Expected behavior

No error as this valid.

pylint --version output

Python 3.6.4rc1

Thanks for the report. It seems that mypy_extensions does some metaprogramming that pylint and its inference mechanism can't quite understand.
