Completed activity messages are now clearer and more concise by showing user feedback first, without an extra title. When an activity includes a note, it is still shown after the feedback so important context remains visible.

Feedback should be the first part of the message without tilte
to make it more concise.

If the activity has a note, the note should be displayed
but after the feedback.

We can also remove the field feedback that was not so useful
since it was only written just before unlink. Feedback is now
passed as another parameter to the template.
