Improvement to capture Audit-log entries for 'Project roles changed' actions.

Audit logs record the array list for the 'Project roles changed' action whenever a user is added or removed from project roles.
This entry doesn't provide clear information on which user(s) is removed/added under project roles.

Actual behavior:

It displays an array list for (Strikethrough)old records and a list of new records.

Expected behavior:
It should display the only entry/record/value that is added or removed for 'Project roles changed'
