deps(update): update webdriver-manager to ^12.0.0

Running `webdriver-manager update` will now by default grab the latest
versions of all binaries (standalone, chromedriver, iedriver, gecko
driver). You can continue to pin to a specific versions using the
command line option. Example `webdriver-manager update --versions.chrome 2.20`. As of this release the latest versions are:

- gecko v0.14.0
- selenium-standalone 3.0.1; however, 3.0.0-beta4 appears to work for
Firefox
- chromedriver 2.27
- iedriver 3.0.0
