User data can't be loaded for peers

[rudolfs]

When I add a new remote to a project, it shows up in the remotes, but the Person data isn't present and the UI shows an error message.

The remotes endpoint returns a 404 when queried for the newly added remote:

Request URL: http://127.0.0.1:40000/v1/identities/remote/rad:git:hnrkp3ubyais3punqwh97k5qutuzz8a7x7igy
Request Method: GET
Status Code: 404 Not Found

I also observe that the Person identity of the tracked remote only appears within the project's namespace and not on the top-level.
