Allow setting values in value type group properties in "on" assignments

Assigning to a group property inside a property value source or
interceptor as part of an "on assignment" is perfectly valid. That is
because while "color" is a value type property, the on assignment means
we're actually setting easing.type (in the example and test) on the
property value source, not the color, and that one is a QObject. The
same goes for interceptors.
