constantize broken when parent != parent by name

see #410 Inflector.constantize uses eval which is slow in JRuby and Ruby 1.9 -- I opened a new ticket because I wasn't sure if tickets marked resolved get watched and re-opened?

class Outer2
  module Why
    TOM2 = 5
  end
  include Why
end

"Outer2::TOM2".constantize #fails

in the wild: "Logger::INFO".constantize fails, which causes picnic to fail.
