[meta] Add messages to assertions in a loop in sped up tests

Problem/Motivation

Recent commits to speed up the tests has changed some test to use a loop instead of a dataprovider without also adding messages to the assertions. The messages are needed to identify which case is failing.

So far, these have been checked. Are there others?
