Bug description:
  [Impact]

   * A previous update made AppStream use modern-style component-ids, thereby breaking the Qt library if it is reading data from the cache and if that data happens to be a desktop-application.
   * This leads to KDE's Discover not displaying applications.
   * The issue was introduced by a patch to the Xenial version of AppStream, and is not present in any other version of the package in Ubuntu, affecting Xenial only.

  [Test Case 1]

   * Update the libappstream-qt package, run Discover: All apps should
  be loaded correctly.

  [Regression Potential]

   * Low, this change affects only the Qt bindings and nothing else. The
  change is also a simple string value change.
