[W|9.725(d)]Task "author" not changed after a nickname change (minor)

[josmow]

pretty simple to do, make a pawn do a bill that takes time, (statue,sword,etc) and change their nickname. the object's crafter identification stays the same, does not seem to stop the user from continuing their work however so its not game breaking.

note: this is for the unfinished project, not the new worker label on the bills.
