windows: aio app run --local testing in the browser issue

## Description
I cannot get any results from Openwhisk via the actions tester in the browser until I disable the firewall. There is one prompt to allow `node` through the firewall, and nothing else for any other process.

See related: #311

## Workaround
Disable all Windows firewall settings.

## Possible Fix
https://github.com/docker/for-win/issues/4391#issuecomment-520420942

Start by reviewing related issue #311 and the linked Docker for Windows issue/comment, then reproduce `aio app run --local` in the browser on Windows with the firewall enabled. Done means the OpenWhisk actions tester returns results without requiring all Windows firewall settings to be disabled.
