warning Field is not callable

[A-Iskakov]

Hello guys,
I get multiple warnings while determine field in Model class, such as EmailField, BooleanField, PositiveSmallIntegerField, PositiveIntegerField, DateTimeField, TextField, NullBooleanField, UUIDField, URLField
The warning everywhere the same:
This inspection highlights attempts to call objects which are not callable, like, for example, tuples.

I have this in PyCharm, is it present in mypy too?

Difference between "callable" and "non-callable" fields in this case is that callable ones have their __init__ method redefined, I assume bug in PyCharm is
(if this is a contents of stub file)

_T = TypeVar('_T')

class ParentField(Generic[_T]):
    def __init__(self):
        pass

class ChildField(ParentField[_T]):
    pass

ChildField will not be callable in source code, according to pycharm.

I am also experiencing this issue in PyCharm 2018.3.3, Python 3.7, Django 2.1

The problem almost fixed in Pycharm 2019.1, except for django.contrib.postgres.field.JSONField
