Many To Many with string based IDs

[smakman]

When following the Many To Many example in the docs: https://vuex-orm.github.io/plugin-graphql/guide/relationships.html#many-to-many

I get the following error when using string based IDs:

TypeError: Cannot read property 'hasIncrementFields' of undefined

Only thing I changed on the User model is:

id: this.attr(null) // instead of this.increment()

Is there a way to get Many To Many work with string based IDs?

Could you check if this is still an issue with the latest release?
