[BUGFIX] Do not log failed HMAC validations in ext:frontend

With #93667 logging of HMAC validation errors caused by potentially
manipulated form submissions has been disabled. The change does
however not consider exceptions handled in the
ProductionExceptionHandler for content objects in ext:frontend.

This change prevents logging of two exceptions caused by potential
manipulated form submissions in ProductionExceptionHandler for
content objects.
