Bug 13790: Add unique id issue_id to issues and old_issues tables

Test Plan:
1) Use a database with existing issues and old issues
2) Apply this patch
3) Run updatedatabase
4) Inspect the database
   a) old_issues should now have a column issue_id starting with 1
   b) issues should now have a column issue_id starting with the number
      of rows in the old_issues table plus one
5) Perform a checkout, note it is written to the database
6) Check in the checked out item, note it is moved to the old_issues table
