[Dbix-class] namespace::clean problems

[Graham Knop]

This looks like a bug to me.  DBIx::Class::Carp tries to call
namespace::clean->import, but doesn't load it first.  And
DBIx::Class::Carp is loaded by ::Schema before it loads
namespace::clean.

An import call on a package that doesn't exist or doesn't define an
import will usually be ignored.  However, if UNIVERSAL.pm is loaded on
old versions of perl (pre-5.10) all packages become Exporters, and
will error on parameters passed to import.
