[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
Assume this is a "singleton" fka "squatter" situation (see [1])...

Then wildCardChildRegistration will be null, so from L220 isAlias will be false, so the result of L225 will always be false.

This means  a singleton/squatter could never be processed as an alias. But such a registration could be an alias.

Are lines 219-200 needed? Can declaring isAlias = true to start and then setting to false and breaking the loop if childRegistration.isAlias() work?
