While updating an unrelated field of an old Tracker ticket, the owner was unexpectedly and automatically unassigned. The ticket owner in question is no longer a team member.
Example:
https://sourceforge.net/p/scummvm/bugs/3860/?limit=10&page=1#d064
(I have 9 more instances of this if that should be helpful.)
We should allow the previous value to be preserved for user fields, even if that user isn't a member of the project any more.
Closed #507.
