Title: Reduce ActiveModel version requirements

I've fixed everything from comments on https://github.com/cgriego/active_attr/pull/84
This patch gives possibility to use active_attr with rails 3.0.2 and higher.
rails 3.0 and rails 3.0.1 has such as_json method implementation:

def as_json
self
end

so some tests fails on it. If we remove this tests, then everything else will be ok.
