Trying to access a closed Dataset object results in an ugly warning

[mmomtchev]

The warning has no functional consequences and can be safely ignored.

It is caused by node-gdal-async using raw getters (as opposed to property getters) which allow console.log to print the actual value instead of geoTransform: [Function] - and in this case Node's internals do not like getting an exception.

AFAIK, it is not possible to have both.

> ds.close()
undefined
> console.log(ds)

This is caused by either a bug in Node.js or incorrect usage of Node.js internals.
