Add possibility to add a message when adding or removing a blacklist entry
for both mail and phone_validation (used for SMS). This replaces the
``action_remove_with_reason`` method.
When updating active flag this is added as a tracking note to avoid having
several messages. Indeed message is concatenated with the tracking itself
instead of adding message for tracking + a message for the log itself. When
a new record is created, a note is logged.
