remove the http(s) proto before removing non-word characters

Domains that start with "s" get chopped because the regexes were in the wrong order.
For example "http://seancoates.com/" became "eancoates.com" because:

* `http://seancoates.com`
* (remove non-word chars)
* `httpseancoatescom`
* (remove proto/prefix)
* `eancoatescom`
