Remove duplicated method

[printercu]

It's redefined on L141.

I'd suggest removing the protected version instead, in case some consumer uses this method.

[printercu]

I can do this. But this one is protected now, so one can use it only with send.

[tbrisker]

Right, now if some consumer of the gem expects the non_audited_columns method to be public this change will break their code, hence it would be better to remove the protected once and not the public one.

[tbrisker]

Oh, now I see what you mean, it is already protected because of the duplicate definition. In that case makes sense to remove the public version.

Thanks @printercu !
