Let's only show cookies for http:// and https:// origins (not for file: or data:
for example).

It looks like it's possible to set cookies on file: origins with
`--enable-file-cookies` flag, are we sure we don't want to show them?

I was thinking about bringing EmptyWidget back but I found out that for data
URLs CookieItemsView isn't even created (which looks like this:

non-http(s) origins (see ResourcesPanel.js). WDYT?
