Upgrade web3.js for latest node.js (<11) support

[schmidsi]

The scrypt packages which is a dependency of web3-eth (and others) does not work with node.js >=11.15. This issue is already solved in https://github.com/ethereum/web3.js/pull/2938, so theoretically it should be sufficient to just update web3 to the latest 1.x version (which happens in this pull-request). Unfortunately, after this update, some of the tests fail :(

I did not have time to find the root cause of this, but just wanted to inform about my failing attempt.

Maybe in the meantime, add something like this to package.json?

    "engines": {
        "node": ">=8.0.0 <=11.15.0"
    },

I can confirm that it works with Node.js@10.16.3 (LTS)

Thanks @schmidsi, I'll look into why the tests are failing!

I think with web3.js having a proper v1 we can also remove the pin, since that was a fix for more unpredictable releases of web3.js previously :).

As far as I know, web3 v1 is pretty stable: https://medium.com/@samuel_91690/1-0-release-web3-js-ddd23d3c8f62

Yep, exactly :).

Will release as a release candidate and test with a few existing examples to make sure nothing else was broken :).
