Passing a Module reference to module throws Error

[justin-equi]

Describe the bug
Some build systems do not expose prototype on Module, so when a caller passes a direct module interface into the module it blows up. I believe this is the actual correct behaviour for the Module object. I ran into this issue with a vitest setup. Seems unlikely this is the only situation where this might be an issue.

Example

//resolvers.ts
export const Mutation = {
  yourMutation(){
... do things.
  }
}

And then the caller sets up the module as following

import { createModule } from 'graphql-modules';

import TypeDefs from './schema.graphql';
import * as Resolvers from './resolvers';

export const YourResolverModule = createModule({
  id: 'your-resolver-module',
  dirname: __dirname,
  typeDefs: TypeDefs,
  resolvers: Resolvers,
});

Will fail with

TypeError: currentResolvers.hasOwnProperty is not a function
