mix ecto.setup broken runs forever

[heyzec]

When mix ecto.setup is run against a clean DB, the task does not run to completion. It seems to be endlessly inserting into the users and course_registration tables. For @shirsho-12, this task ran on his computer for 30 minutes with no end in sight.

git bisect identified the first bad commit as 5203125.

For now, the workaround its to checkout to this commit's parent (71192c3), running mix ecto.setup on this, checking out to your desired commit, and then running mix ecto.migrate.

@josh1248 Can we revert this part of the changes?

[josh1248]

yo go ahead, the changes were meant to load test the assignment pagination feature which we did a few months back, forgot to change it back for the pr

[josh1248]

could be because some other changes have slowed down the db? just be careful and make sure any recent changes arent degrading performance
