`--ignore-bodies-if-inherits-from` doesn't seem to work

[andreyfedoseev]

Hello,

I'm trying to use the --ignore-bodies-if-inherits-from option to drop false positives for class attributes in my GraphQL schema, but it doesn't to work.

This is easily reproducible:

# mymodule.py
import graphene


class SomeQuery(graphene.ObjectType):

    this_field_is_used = graphene.String()

$ deadcode ./mymodule.py --ignore-bodies-if-inherits-from graphene.ObjectType         
mymodule.py:4:0: DC03 Class `SomeQuery` is never used
mymodule.py:6:4: DC01 Variable `this_field_is_used` is never used

$ deadcode ./mymodule.py --ignore-bodies-if-inherits-from ObjectType 
mymodule.py:4:0: DC03 Class `SomeQuery` is never used
mymodule.py:6:4: DC01 Variable `this_field_is_used` is never used

I'm using deadcode==2.4.1

P.S. --ignore-definitions-if-inherits-from doesn't work either.
