_forwardMigrate2(): user.roles.filter is not a function

Attempting to upgrade from version 2 to version 3, I received the following error:

> Package['alanning:roles'].Roles._forwardMigrate2()
TypeError: user.roles.filter is not a function

This was on v3.1.0 I applied all updates and got the same error on v3.2.0

That means you have a user in your database where the property roles is neither null, nor not existing, and still something but an array ... Can you please check this up? Try to run this command directly on your database (e.g. using Robo 3T):

db.getCollection('users').find({
  roles: {
    $ne: null,
    $not: { $type: "array"  }
  }
})

All of my users have an object as the roles property:

, 
    "roles" : {
        "__global_roles__" : [
            "admin"
        ]
    }

Therefore, I went back and checked, and just realized I was running v1 and not v2. I apologize for my oversight. I'm good to go now.
