ActiveRecord::insert() and ActiveRecord::update() refactoring

Fixes the variable name

Fix in docs

Changed based class to base class

Fix attaching behavior via config

The intent may be to detach behaviors defined in behaviors().
In the original implementation, if these behaviors() are not yet attached, they can not selectively be detached.
