Don't eager load a class needing qpid_proton loaded at load time

This class can't be eager loaded because not all pratforms install qpid_proton
and we need qpid_proton's class at load time.  We can't install qpid_proton on mac
but also don't want to install qpid's dependencies in CI in various providers, core,
etc.
