A little constantize update

[semaperepelitsa]

I was also able to reduce safe_constantize to the following without breaking any tests and I don't really understand what is the point in the deleted lines. Maybe someone could provide some tests explaining and covering them?

def safe_constantize(camel_cased_word)
  begin
    constantize(camel_cased_word)
  rescue NameError => e
  end
end

These changes seem fine to me. Were you able to run even the railties tests with these changes?

Yes, railties tests all pass.
