Ticket Activity - Responsible user format

[paulsputer]

When changing the responsible user via the ticket page the dropdown lists users in the format:

<user alias> (<user name>)

However, when looking at the ticket activity page changes in responsibilty are displayed only as:

<user name>

Depending on configuration this may be difficult to identify the user.

Ideally this should show responsibility changes in the same format as shown in the dropdown.
