Global scope of pivotModel not included in whereHas()

This scenario requires following things:

• model with belongsToMany relationship using pivotModel
• pivot model which has a global query scope

The problem: queries using whereHas are not applying the global scope of a pivot model. Query generated by the builder:

select * from `users` where exists (select * from `tags` inner join `user_tags` on `tags`.`id` = `user_tags`.`tag_id` where `users`.`id` = `user_tags`.`user_id`)

should be:

select * from `users` where exists (select * from `tags` inner join `user_tags` on `tags`.`id` = `user_tags`.`tag_id` where `users`.`id` = `user_tags`.`user_id` and `user_tags`.`active` = 1)

Package version

Node.js and npm version

Sample Code (to reproduce the issue)

/** @type {typeof import('@adonisjs/lucid/src/Lucid/Model')} */
const Model = use('Model')

class Tag extends Model {
}

class User extends Model {
  tags () {
    return this.belongsToMany('App/Models/Tag')
      .pivotModel('App/Models/UserTag')
  }
}

class UserTag extends Model {
  static boot () {
    super.boot()

    this.addGlobalScope(
      query => {
        query.where('active', true)
      },
      'foo'
    )
  }
}

// the query:
User.query().whereHas('tags').first()

@thetutlage thanks! It solves this issue.

Btw, I have a question - is it possible to use scopes of pivotModel in whereHas query? It could be quite helpful.

A quick example (using soft-deletes package):

User.query().whereHas('posts', qb => {
  qp.withTrashed();
});

@radmen Thanks for sharing a sample repo, it helps. Want to try it from Github as see if latest commit fixes the issue for you or not?
