 This ticket is prodded by the cause of #27866.

 We were able to add a few tests for the site and network finding process
 in #27003 during 3.8 development, but we're still limited by the structure
 of ms-settings.php pretty severely.

 We should be able to test how `$_SERVER` requests turn into expected
 `$current_site` and `$current_blog` globals.

 In an ideal world, we could also harness something in our tests to change
 the `DOMAIN_CURRENT_SITE` and `PATH_CURRENT_SITE` constants on every test
 to test various situations. If nothing else, we can initiate phpunit with
 different values.
