Do not allow setting reminders on read-only calendars

[grrosminet]

On read-only calendars you don't allow to go to edit intent.
you must refuse to set reminders too

(v1.0.34 fdroid )

I think setting reminders locally could be okay (not sure about what the standard or the Android calendar storage API says). But the event should definitely not be set to "dirty" (which could trigger sending it to the server sometimes which will also cause problems).

I don't think modifications should be allowed.

What happens when a user modifies the reminder and the server version gets an updated reminder? Which one to prefer?

As said on the davx5 issue, I suggest to block this and ask the user to create a new reminder elsewhere, as the calendar is read-only.
