Update the user migration to include missing fields.
To test:
- run the profile picture migration "drush mim drupalorg_migrate_user_picture_files"
- run the field collection migration "drush mim drupalorg_migrate_field_collection_contribution_role"
- reset the last imported user variable "drush state:set drupalorg_migrate.drupalorg_migrate_users_last_record 0 --input-format=integer"
- run the user migration "drush mim drupalorg_migrate_users"
