Pass "primary mix-in" to AnnotatedFieldCollector from AnnotatedClass

[cowtowncoder]

A very minor inefficiency is that whereas AnnotatedMethodCollector is passed the primary mix-in explicitly, field collector isn't. But it probably should. While doing this, may also see if supertype information could/should be passed.

Oh, and the reason? Avoid one more lookup for known information; not just/mostly for cost (simpleish function call, lookup), but to reduce any chance of dynamic lookup producing different result (single canonical evaluation).
