Full screen event editor doesn't show calendar's name when calendar is readonly

[Mer0me]

Steps to reproduce

1. Share your calendar read only to another user
2. Create an event
3. As the sharee, open the event with the full screen editor : calendar's name is missing
4. On the simple view, the calendar's name is visible.

Expected behavior

Full screen editor should display, at least, all the informations visible in the simple editor, even if the calendar is read only.

Actual behavior

Simple editor :

Full screen editor :

(By the way : the full screen editor is very empty and ugly in this use case, it should be redesigned)

Hi @Mer0me

I agree the calendar name should be visible in read only mode
