Use any-promise for everything

[lionello]

any-promise was already in use in some submodules, except these two were using bluebird. This patch uses it uniformly.

One reason for this PR is that we noticed that sometimes promise rejections were not triggered.

As we were debugging we saw some DOM elements were created within promise management code by the bluebird library, instead of using the native Promise object available in the browsers (except IE 11 & Opera Mini.

The any-promise library also says:

NOTE: You probably want native promises now
...
If no preference is registered, defaults to the global Promise for newer Node.js versions. The browser version defaults to the window Promise, so polyfill or register as necessary.

We were concerned that such DOM trickery - which is not really necessary in 2018 - might interfere with web frontend frameworks (eg Vue.js), especially in their development mode with hot-code-reload.

So far we couldn't prove such interference because our issues seems stem from a combination of regressions and bugs in geth and web3.js, but it definitely helps the debugging experience if we don't have to wade through ancient DOM-magic-promise code in addition to the million other layers of the software.

+1 because this fixed #1386 for me.
