DRF ChoiceField does not work with Graphene-Django

[jmp]

When using SerializerMutation with Graphene-Django 3.0.0b7, DRF's ChoiceField doesn't seem to work correctly:

1. Two identical enum types (but with different names) are created in the GraphQL schema
2. Using any of the choices in the mutation input results in an error like"\"foo.BAR\" is not a valid choice."

Minimal demo project

Reproduction steps:

1. Clone the demo project:

   git clone git@github.com:jmp/graphene-django-enum-example.git

2. Set up the project:

   python3 -m venv .venv
   source .venv/bin/activate
   pip install -r requirements.txt

3. Generate the GraphQL schema:

   python manage.py graphql_schema --out schema.graphql

4. Open schema.graphql and you can see an enum AppDummyFooChoices defined as

   enum AppDummyFooChoices {
     """First"""
     FIRST
   
     """Second"""
     SECOND
   
     """Third"""
     THIRD
   }

   In the schema, you can also see a duplicate enum defined as

   enum foo {
     """First"""
     FIRST
   
     """Second"""
     SECOND
   
     """Third"""
     THIRD
   }

5. Run the project, navigate to http://127.0.0.1:8000/graphql and run the following query:

   mutation {
     dummyMutation(input: {
       foo: FIRST
     }) {
       id
       errors {
         field
         messages
       }
     }
   }

   You will get an error:

   {
     "data": {
       "dummyMutation": {
         "id": null,
         "errors": [
           {
             "field": "foo",
             "messages": [
               "\"foo.FIRST\" is not a valid choice."
             ]
           }
         ]
       }
     }
   }

Expected behavior:

1. In the GraphQL schema, there should be only one enum type AppDummyFooChoices.
2. There should be no error when trying to use the enum value FIRST in the mutation
