Stop autogenerating examples where we already have one

If an object definition already has an example, we shouldn't try to extend that
definition by adding examples derived from the individual properties. Doing so
is confusing, and there is no way to inhibit it when it is not desired. It's
also not what the RapiDoc viewere does, so we end up with examples being
inconsistent.
