Datastore tests fail if there's invalid entities in the DB #2469
Description
Repro:
- Create an entity in the visits table with empty IP address
- Run the tests
- Fail!
Fix:
- Remove entities with empty IP addresses
- Run the tests
- Success!
I am not sure who the right person to update this is but we should either clean up the visit entities before running the test or make the tests resilient to empty IPs.
