`sweep_up!` causes an error in a SubClass

[danbernier]

If a base class includes TinySweeper and defines some swept fields, and you call sweep_up! on its subclass, you get this error:

NoMethodError: undefined method `each' for nil:NilClass
        from ...tiny_sweeper-0.0.5/lib/tiny_sweeper.rb:20:in `sweep_up!'
        from ...tiny_sweeper-0.0.5/lib/tiny_sweeper.rb:51:in `sweep_up!'

May be worth creating a trivial spec to reproduce it

Yeah, I will. I just found this, & wanted to not forget about it.
