[rt-users] Easily fixing missing prinicipal

[Jerrad Pierce]

I restored everything that seemed to be pertinent/to match the user
ID, and the web interface works, and there may or may not be errors in
the log...

But when I try to shred (with remapped ID) the restored user I get:

Couldn't wipeout object: Can't call method "Type" on an undefined
value at /opt/rt3/bin/../lib/RT/Shredder/GroupMember.pm line 90.
