Added support for access revoking

[ishmelev-sp]

An update to support features from the new release of uplink-c, according to messages from this PR.

Notes:

1. It works on macOS, but I couldn't test it on Windows, because I have no one. Could anybody do it? It needs only to run npm install, configure a path to .dll (like it's described in README.md), and run npm test.
2. Here I propose a new way to handle the results of promises with chai-as-promised library. It's more convenient than waiting for the result and checking it.

Thanks @ishmelev-sp - we'll review this week.

@ishmelev-sp - just an update: this looks like it will be in the queue for late next week for review. Thank you very much for the submission!

[ishmelev-sp]

Guys, do we have any updates?

[kmozurkewich]

Hi @ishmelev-sp - no updates as of now. This is in the queue, however, code review updates are a lower priority task in sprints right now.

Hi, @ishmelev-sp, I got some issue while running test with "yarn test"

The only failed is with "Revoke access"
I attached screeshot, and please give me feedback

[ishmelev-sp]

It's strange, thank you. I had tested it before, all tests passed. Hmmm... maybe I missed something....
I will check it in the nearest time.
