enhancement Display name of user who completed an activity in the completed activities list

[Gareth Cantrell]

In the activity list, the name of the assigned user or team is displayed, however we'd also like, specifically in the case of a team assignment, to see the name of the user who completed the activity, similarly to how it is displayed when you click on the individual activity.

Currently we have to copy this info (completion time and completion user) from the activity into multiple custom fields so the data is visible in the details section.

Having this extra info in the activity list would satisfy the requirements from our external auditors and also allow us to free up 12 custom fields (in this particular scenario)
