Re-Fetch Missing Repository-Info
Currently, the Panorama-View redirects back to Home, if only the repoId is set in the shared model, but not the repoName. Theoretically, the repoId should be all the client needs, in order to get all required info from the backend, however the repoName and repoUrl are not currently included in the RepositoryInfo JSON-Reponse.
See TODO in Panorama/Update.elm
