In case an application gets disabled the level is set to "experimental" if it does not contain a `shipped` tag. This can for example be reproduced by installing the documents app from the appstore and then disabling it. Or cloning an app from git.
With this change the controller will now load the level of the application from the appstore if a valid OCSID has been provided.

Otherwise every time the AppStore was opened a lot of connections to the AppStore server were made which resulted in a terrible performance.
This changeset will cache the response for a sensible time so that only the first request will be somewhat slow.
Performance changes:
- Loading a category took previously more than 3 seconds on my machine. Now for every follow-up request it takes less than 200ms, resulting in a performance gain of 1950%
- Loading the category list took previously about 750ms - now it takes 154ms, a total performance gain of 395%
