Fix - openChrome won't open default browser (using Canary)

Created by: n3tr

fixes #1213 (closed)

I accidentally changed "Chrome" to "Google Chrome" in #1165. It forces to open Chrome Stable instead of default browser in system-wide (eg. Chrome Canary).

• Use “Chrome” instead of "Google Chrome", It will try to use current active browser. otherwise, use default.
• If no “Chrome” aren’t running, will fallback to opn(url)
