Automatic cookie domain does not return root view on subpage URLs

[sjhcockrell]

Example:

$ ./phantomas.js --url=https://www.cnn.com/money --cookie='mobile=on'

PhantomJS cookie will be set having a domain of:

{
  "name": "mobile",
  "value": "on",
  "domain": ".cnn.com/money"
}

I broke it, so I'll fix it.
