Cache enum types in attributeFields doesn't work as expected

[alirizwan]

When calling attribute fields multiple times on same model, duplicate enumtypes gets created with an error: Error: Schema must contain unique named types but contains multiple types named "UserroleEnumType".

Why was this closed? This still seems like an existing bug.

Actually, I solved it by doing this:

const options = {
    cache: {},
    commentToDescription: true
  };
const fullModel = attributeFields(model, options);
options.allowNull = true;
const looseModel = attributeFields(model, options);
}

Seems to work well
