Fix AppDetails API for Share Link to Installer File feature

* When the Scriptoria instance was moved from one AWS account to another
  we had to change the bucket name to be able to copy the files. We
  updated all the urls in the databases when we did the migration.
  However, the play-listing-manifest.json still have the old bucket
  name in the path. This is used by the Share Link to Installer File
  feature to get metadata about the app (title, description).
* Change the hostname in the url stored in the JSON file to have the
  same hostname of the artifact retrieved from the database.
