Fix some pagination/redirect issues for repositories

Summary:
Ref T10923. Paging wasn't being applied correctly when creating //new// repositories after API changes.

Also, the first redirect after creation wasn't sending users to the right place.

Test Plan:
- Created a new repostiory, got redirected properly.
- Verified that new repostiory flow has the correct fields (name, callsign, etc) and Conduit API has the correct fields (everything).
