No longer warns on res.close event

[msmol]

See: nodejs/node#20611

res.close is always triggered and is no longer considered and error or warning condition

Addresses: #21

I think that change in #20611 is incosistent with the documentation of close event - "Indicates that the underlying connection was terminated before response.end() was called or able to flush." - this is not true anymore - event close is called always. Either the documentation should be changed or this PR should be reverted or fixed. I don't know if it is intended behaviour (then isn't it a API change - SEMVER-MAJOR?), but from my point of view only unintended side efect of the fix. Previous functionality can be achieved by testing res.finished in close event...
