Event header: Remove date directly above other date (Z#23245589) (#6524)

* Event header: Fix wrapping of date in h2 header (Z#23245589)

This was already correct if the header was a h1

* Revert "Event header: Fix wrapping of date in h2 header (Z#23245589)"

This reverts commit 3d25316fe3.

* Event header: Remove date directly above other date

This removes the date from the <h2> option used when a header image is
uploaded and the header should still be shown. Rendering the date here
makes little sense, since the infobox with the date is always just a few
lines below. It still makes sense for the <h1> option where it becomes
part of the site header.
