DefaultConverter: fix bug converting to Collection

It is straightforward to convert from a Collection subclass
(e.g., ArrayList) to a Collection. It is just a simple cast.

This bug prevented such casts from taking place, due to
over-eager precedence of Collection-specific handling.

We really need to rewrite this stuff; see:
#109
