Unbound enum values are None when used in arguments

When used as a mutation input, enum parameter should be str, but actually is None.

def test_executing_mutation_takes_enum():
    type_defs = """
        type Query {
            _: String
        }

        type Mutation {
            eat(meal: Meal!): Int!
        }

        enum Meal {
            SPAM
        }
    """

    mutation = MutationType()

    @mutation.field("eat")
    def resolve_eat(*_, meal):  # pylint: disable=unused-variable
        assert meal == "SPAM"
        return 42

    schema = make_executable_schema(type_defs, mutation)

    result = graphql_sync(schema, 'mutation { eat(meal: SPAM) }')
    assert result.errors is None
    assert result.data == {"eat": 42}

We’ve fixed this on master, but in meantime to release hotfix would using ariadne.EnumType to set those values explicitly in python:

meal = EnumType("Meal", {"SPAM": "SPAM"})

Thanks for report!
