[WFCORE-57] : Deprecated resource is present in r-r-d of /subsystem=security/security-domain=*

Aliases were displayed without their description even if include-aliases is not set to true.
Now the operations 'read-resource-description' and 'read-children-types' won't display aliases per default.

Jira: https://issues.jboss.org/browse/WFCORE-57
This else block will also be triggered when readChild==false due to the "childReg.isRemote() && !proxies" test, so it's not just about aliases.

Also, won't the behavior here vary depending on the order of things? So we have service=alias and service=not-alias. If "not-alias" is processed first, then when we process "alias" we have "children"=>"service"=>"model-description" so the L321 test passes and we add "children"=>"service"=>"model-description"=>"alias". But "alias" is processed first, it won't get added.
