Fix intermittent unit test failures

The following tests have been failing recently:

 test_update_add_locations_status_exception
 test_update_replace_duplicate_locations
 test_update_replace_locations_status_exception

They were querying storeurl.com which redirected to
www.hugedomains.com, and unexpected exchanges, eg:

 HTTP/1.1 302 Found.
 Cache-Control: private.
 Content-Length: 183.
 Content-Type: text/html; charset=utf-8.
 Date: Wed, 01 Apr 2015 19:05:15 GMT.
 Location: http://www.hugedomains.com/domain_profile.cfm?d=storeurl&e=com.
 Server: Microsoft-IIS/8.0.
 X-Powered-By: ASP.NET.
 Connection: keep-alive.

Mocking out the get_size function prevents these real connections.
