Calendar module update 16.0.28

@prophead @richie
Could you please tell me what exactly is your setup? in particular:

  • How many calendars you have and the type (OAuth, CalDav…)
  • How the match for the route is setup (are you using Time Conditions with calendar mode? Calendar groups? something else?)

This is definitely a consequence of my PRs and I’m sorry for that, I’m trying to debug the problem but it doesn’t show up for me
