feat(provider): adjust provider callbackurl handling

[Phil91]

Description

When the provider callback url is removed the trigger provider callback steps are set to done and the await auto setup step is created

Why

If a offer subscription process is in progress and the provider callback url is removed by the provider it might occur that the process is stuck since the next step would be to trigger the provider callback, which must not be triggered anymore
