Code Issues Proposed changes

Delay description association proxy construction 

Association proxies cannot be constructed in the mixin because they
will be shared between all models that inherit from it. This means
they all share one and it will effectively be broken for all but the
first to load it.

This changes it to a declared attr like the others to make sure it's
not constructed until each model inherits from it.
