Apps with multiple sources are not properly supported

Note the revision and revisions fields - the first versions were implemented to just load the revision field, but apparently its possible to have multiple application sources.

This breaks the rollback view for sure, perhaps also has some implications for syncing.

The temp fix applied in #15 likely doesn't fully solve the problem. I'll need to do some spelunking in more complicated app setups to see what's actually needed here.

Personally, I don't need this feature so I have no reason to implement it.
If enough people request it, I will consider it.

Please if you care for it, give the issue a 👍
