Title: fixes issues #260

Trying to rw_config a nil value where the default_value is also nil ( for instance, using omniauth and not using "login" or "password" credentials) will give raise a Stack Too Deep exception.

Patch simply checks if the default_value is nil, and if so leaves the key empty in config (which will return nil anyway.)
