Revoked participants are still redirected to the event live page and can not visit the event info page while the event is live

[Apfelwurm]

When currently a participant is revoked, the participant will still be redirected to the event live page and is unable to access the event info page after the revokation.

Tested in this case with a staff ticket and an online event, but should also be the case with the other tickets.

&& ($participant->revoked == 0) should be checked everywhere.

This applys for the HomeController in index (and in isActiveParticipant if the big PR is merged)

Also the User models setActiveEventParticipant has to be checked.

Most likeley there are also additional other places, where such checks are nessecary, also the logic should be refactored and centralized.
