HPCC-18037 Fix 3 bugs related to ESP AuthDomain setting

1. Generated esp.xml has an empty AuthDomains section when there is a
AuthDomain setting in environment.xml; 2. generated esp.xml should not
have AuthDomains section if no AuthDomain setting in environment.xml;
3. the name of AuthDomain should be read from the '@domainName' from
AuthDomain setting.
