- Added a failing test and made it pass.
- Dragged tasks around within a milestone column:
- Before patch: they got bogus project swaps on every other move.
- After patch: projects didn't change (correct).
- Dragged tasks around between normal and milestone columns.
- Before patch: worked properly.
- After patch: still works properly.
Here's what the bad changes look like, the task is swapping projects with every other move:

The "every other" is because the logic was trying to do this:
- Add both the parent and milestone project.
- Whichever one exists already gets dropped from the change list because it would have no effect.
- The other one then applies.
- In applying, it forces removal of the first one.
- Then this process repeats in the other direction the next time through.
