Summary:
Depends on D20041. See PHI1046. If you do this:
- Create a parent project called "Crab" in Space 1.
- Create a milestone called "Left Claw".
- Shift "Crab" to Space 2.
- Create a milestone called "Right Claw".
...you currently end up with "Left Claw" in the wrong `spacePHID` in the database. At the application level it's in the correct space, but when we `WHERE ... AND spacePHID IN (...)` we can incorrectly filter it out.
Test Plan:
- Did the above setup.
- Saved "Crab", saw the space fix itself.
- Put things back in the broken state.
- Ran the migration script, saw things fix themselves again.
