CourseTask ordering is assigning same order number to CourseTask

[mblayman]

A customer pointed out that some tasks are showing up out of order. When I investigated the course in question, some of the tasks had an underlying order field with the same value. The best working theory that I have is the bulk creation is to blame. The customer confirmed that the tasks in question were likely created with the bulk creation tools.

In my local testing, I'm not able to replicate this problem with any of the bulk task creation. I tried:

• Bulk adding to the end
• Bulk adding in the middle
• Deleting some stuff
• Deleting multiple things at once

After all of these operations, the order remained intact.
