When running the mybb.rb importer script I get the following error.

```

creating users
/var/www/discourse/script/import_scripts/mybb.rb:51:in `block in import_users': undefined local variable or method `users' for #<ImportScripts::MyBB:0x007f1cb24e0108> (NameError)
        from /var/www/discourse/script/import_scripts/base.rb:670:in `block in batches'

        from /var/www/discourse/script/import_scripts/mybb.rb:189:in `<main>'

```

I was following these exact steps from a previous user who was importing their database from MyBB to Discourse when the error occurred.
