#21837: Site search for a domain by text fails in subdomain installs of multisite
with www in primary domain

 To reproduce:

 1) Create a subdomain network install where the main site's domain
 contains www
 2) On the Network Admin->Sites search for an existing site based on the
 domain name, such as some* to find somedomain.domain.com.
 3) Search returns "No sites found." even when the site exists and was
 searched for using a valid technique.

 I've tested the problem on Apache and Nginx servers, with Twenty Eleven as
 the theme on the main site, and network activated plugins.  Existing sites
 can never be found by domain name.

 Subdomain installs in a network are allowed where the main site is
 www.domain.com. DOMAIN_CURRENT_SITE in wp-config.php points to
 www.domain.com.  But blogs.domain stores the domain of a multi-site site
 named somedomain as somedomain.domain.com (without the www).

 As a result, any site search for a domain based on text (the name of the
 domain) fails because of how the query is built on lines 70-73 of wp-
 admin\inludes\class-wp-ms-sites-list-table.php.  A search for some*
 produces a query that searches for some%.www.domain.com instead of
 some%.domain.com; the result is that nothing is ever found.

 Searches based strictly on site ID work fine.

 Possible fixes: 1) leave as is but warn that subdomain network installs
 where the primary domain includes www will have a broken site search (not
 ideal) and encourage no www on primary site of a subdomain network install
 or 2) check if the primary domain contains www and strip it out prior to
 building the query (ideal).
