Summary

Jira creates a user named ‘anonymous’ for Trac tickets, which have no owner set.
Clearly, no user should be created and ticket should be unassigned in JIRA.

Steps to Reproduce

1. On Trac create tickets with no owner (unassigned)
2. Import trac to JIRA.

Expected Results

• Jira creates a ticket, and correctly leaves it unassigned.

Actual Results

JIRA creates a user anonymous and assigns the ticket to that user.

Workaround

• remove the wrong user manually.
