Since upgrading to 4.9.0, a big fat red message appears at the top of each page, warning me against the use of ad blockers:

Dans le cas où vous utiliseriez un bloqueur de publicités, veuillez le désactiver pour ce site afin de vous assurer que Matomo fonctionne correctement.

Expected Behavior

Back to pre-4.9.0 behaviour: no such messages.

Current Behavior

The message hideous and non-dismissable. Whether I'm using an ad blocker is absolutely none of Matomo's business.

Context

Happily upgraded from the previous release to 4.9.0, and wow! Quite a change from the usually seamless upgrade path!
