Another bug (should've been in another issue, but might as well fix it here).

Here's a version history of an item which was published 18.10, then unpublished 02.11, then published again 13.11:

A report from 01.11 until 13.11 looks like this:

The item was already online on the "from" date, so we should find a published version before this date (which happened 18.10) and compare it with publishing from 13.11 + show a subtitle that the item was offline from 02.11.

With the latest change (where we look for a published version before the From date) we should never start the report with "Item went offline", as far as I understand.
