Try to interpret last cmdline argument as url
Try to interpret last cmdline argument as url

The cased treated before were very limited and unlike other browsers e.g

  - `firefox [OPTIONS] [url]`
  - `chromium-browser [OPTION] [PATH|URL]`

This commit assumes (like other browsers) that the last argument
 is an url and tries to interpret it as such.
 If that fails, then it simply returns `undefined`, as before.

Resolves brave/browser-laptop#9193 opening URL from external application (Thunderbird/LibreOffice) does not work any more
