There were some constructors in the DTOs which allowed construction of
DTO which weren't fully initialized. These constructors have been made
private, as they are still used in the 'fromJson' methods. Additionally,
a constructor with all required parameters to fully initialize the
class has been added.
Additionally, the Loader class has been modified, since it no longer can
assume it is able to default construct the parameter type. The parameter
is now stored as an optional.
Closes #15
Due to some errors within DeviceProfile and how nullables were
serialized, an invalid request was made and the
/Sessions/Capabilities/Full would give an 400 response back.
Besides that, ApiClient would generate a DeviceProfile before all
properties from QML were read. This has been fixed by implementing
QQmlParserStatus and only generating the device profile after all
properties are set.
