Added default names in the commands for lazy loading

[22h]

We are using the OAuth server bundle in a large application and we have noticed that the commands are always loaded when called from the console. So we would be happy if the change is accepted.

See documentation for lazy loading: https://symfony.com/doc/current/console/commands_as_services.html#lazy-loading There are no negative effects.
