bind fails

[jcguu95]

In bind-test.lisp, bind fails in that arbitrary symbols don't seem be bind well with structs.
I tested this with (should-test:test :package (find-package :rtl)).

The error message:

When attempting to read the slot's value (slot-value), the slot RUTILS.BIND::J is missing from the object #S(DUMMY-STRUCT-FOR-BIND :I 8 :J 9). It has a slot RUTILS.TEST::J, while RUTILS.BIND::J is requested.

The root cause may be the same as #77
