fae76393bd test: Avoid F541 (f-string without any placeholders) (MarcoFalke)
Pull request description:
An extra `f` string-prefix is mostly harmless, but could be confusing or hint to a mistake where a format argument was forgotten.
Try to avoid the confusion and mistakes by applying the `F541` linter rule.
