Fix some pagination/redirect issues for repositories
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.
- 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).
