Problem

When attempting to rank or order issues in the Kanban backlog, it fails with an error shown on the UI.

Steps to Reproduce

• Create a Kanban Board with some issue tickets
• Configure the board and navigate to "Columns"
• Enable the backlog by adding at least 1 status to "Kanban backlog"
• Unmap all other columns. At this point, only the "Kanban backlog" will have a status mapped
  
• Attempt to rank issues.

Expected Results

Issues can be ranked just fine.

Actual results

Ranking operation fails with an error in the UI.

Workaround

Ensure that there is at least 1 status mapped to a column.
