(Attempt to) get rid of deprecated app dep wurl

This one may be problematic, as it used to do TLD stuff:
https://github.com/websanova/node-url/blob/7982a613bc/wurl.js#L4

So, the new WHATWG-URL-based implementation will consider
`asana.com` to be "external" to `app.asana.com`, contrarily to before.
Given the nature of Nativefier, I think it's actually what to expect,
that in this case your "out of the app", and in e.g. asana landing's page,
which you'd expect to see in your browser.

Let's see if users disagree with that.
