CLI: Fix open browser handling in interactive CLI

[medikoo]

When watching Steve's first steps demo (internal) we can notice that opening a browser window to set up a new provider doesn't work.
It appears bug on our side is that we pass ANSI colors decorated URL to open command, and that's not a valid URL. Unfortunately, this library doesn't report on that, but just silently runs it (with no effect). This patch fixes that.

Additionally upgraded the open browser logic, and at the same time unified it with the one we use in the dashboard plugin for logging in. There's no longer a need to keep hardcoded internally open implementation as we dropped support for Node.js v6 with v2 major.

Nice!

Great catch, I thought that this issue with browser not opening was caused by the fact that Steve was using VM
