Dynamic constant issues in Constables

[ljnelson]

As an arbitrary example see:

https://github.com/microbean/microbean-construct/blob/v0.0.15/src/main/java/org/microbean/construct/constant/Constables.java#L111

That should be:

ClassDesc.of(Domain.class.getName())

…because the implementation of the interface method may override the return type.
