Fix Ampache API not working on ownCloud 10.14.0

The ownCloud version 10.14.0 has changed the Entity base class and any
classes (indirectly) inheriting it are no longer allowed to have a
constructor taking arguments. Hence, we need to construct our "All
Tracks adapter" playlist in the Ampache API a bit differently.
