Describe the Bug

If a generic type implements an interface, and is registered as an extra type, it is not being recognized in the schema.

from typing import Generic, TypeVar
import strawberry

T = TypeVar('T')

@strawberry.interface
class Abstract:
    x: str = ''

@strawberry.type
class Real(Generic[T], Abstract):
    y: T

@strawberry.type
class Query:
    @strawberry.field
    def real(self) -> Abstract:
        return Real[int](y=0)

schema = strawberry.Schema(Query, types=[Real[int]])
print(schema.execute_sync('{ real { __typename } }'))

raises Abstract type 'Abstract' was resolved to a type 'Real' that does not exist inside the schema..

System Information

• Operating system: not applicable
• Strawberry version (if applicable): 0.195

Additional Context

This worked prior to v0.195. IntReal is present in the schema, but the error references type Real.
