For class Foo with has_many Bar with a default_scope, I believe foo.bars should be scoped. It currently is not, but foo.bars.all is.

Steps to repro:

Create a model Foo with a has_many to model Bar.
Create an attribute in Bar on which to scope.
Create a default scope for this attribute.
Add some instances of Bar to foo.
Try both foo.bars and foo.bars.all, the first one is scoped, the latter one is not.
