Reflection: add regression tests for lazy initialization errors

Add tests for the four error cases in
`reflection_property_check_lazy_compatible()`, as triggered by both
`ReflectionProperty::setRawValueWithoutLazyInitialization()` and
`ReflectionProperty::skipLazyInitialization()`. While some of these errors are
covered by existing tests, having all of the errors in one place will make it
easier to see the changes when the error messages are improved.
