Show re-enrollment errors for workflow on activity timeline
When you re-enroll a contact in a worklow, and this re-enrollment fails because the contact is already in the workflow. It doesnt' show up on the contact record (only in the enrollment history of the workflow itself). It would be helpful if a error message would show up on the activity timeline of the contact. Ideally it would be helpful to be able to receive notifications about this failed attempt as well.
