Wikimedia Bugzilla is closed!

Find and remove any wikipedia specific logic hardcoded in wikibase.

Tim mentioned several here: https://bugzilla.wikimedia.org/show_bug.cgi?id=38822#c7

Full quote:

In ItemView.php:

/**
 * Returns a list of all the sites that can be used as a target for a site
link.
 *
 * @static
 * @return array
 */
public static function getSiteDetails() {
...
    if ( $site->getType() === Site::TYPE_MEDIAWIKI && $site->getGroup() ===
'wikipedia' ) {

The autocomplete feature that this function services also references Wikipedia
in a message (wikibase-error-autocomplete-connection). 

There doesn't seem to be any way to populate the sites table with data other
than the data that comes from meta.wikimedia.org, I had to patch
Utils::insertDefaultSites() to set up my test instance.

populateInterwiki.php also unconditionally references Wikipedia.
