[IMP] event: remove confusing event tour "Communications" steps

This commit removes a few tour steps from the event main tour that required the
user to configure a few "Communications" on the event.
As these steps are a bit tricky and are absolutely not required for a first
overview of the capabilities of the app, they were removed to ease onboarding.
