Can't Enable Issue Action Column after Upgrade to 6.1.x

Summary

The action icon (gear, cogwheel) is missing for one or more users after upgrading to JIRA 6.1 and higher.

Steps to reproduce

1. Bring up a JIRA 6.0.x instance
2. Access the issue navigator in (List view) and click on Tools -> Configure Columns
3. Disable 'Actions' column
4. Stop JIRA and upgrade to 6.1.x

Expected result

Should be able to re-enable the 'Actions' column in the new Column menu (issue navigator)

Actual result

JIRA 6.1.x removes the Configure Columns option from the Tools menu, and makes it impossible to restore

Workaround

1. Backup the JIRA database.
2. Stop JIRA.
3. Run the below update query on the database:

   UPDATE propertynumber
   SET propertyvalue = 1
   FROM propertyentry
   WHERE property_key='user.show.actions.in.navigator'
   AND propertyentry.id = propertynumber.id
   

4. Start JIRA.
5. Test! If there's any problems, restore the backup.
