[Dbix-class] Calling new on a MooseX::NonMoose resultset fails

[Steve Nolte]

Calling new_result on a ResultSet that is built with MooseX::NonMoose
works fine, but just calling new does not.  Can someone please help
explain how to fix?  We have a lot of old code that calls new so just
using new_result is not an easy solution.

I've created a minimal project to troubleshoot:

Thanks,
