Adapt for SNS support dropped from hipposys:domainrule, hipposys:domain and hipposys:moduleconfig in CMS v12

REPO-1665 and REPO-1719 dropped SNS support from hipposys:domainrule, hipposys:domain and hipposys:moduleconfig in CMS v12.

As a result, when comparing a CMS v11 with v12 repository using jcrdiff, this now leads to a mismatch between nodes of these types as jcrdiff explicitly distinguishes between SNS enabled and non-enabled child nodes (using indexed names, or not).

The easiest way to still verify and compare a v11 and v12 repository through jcrdiff is to 'fake' (force) SNS enablement for child nodes of these node types.

This of course is only a temporary fix, and for v12-> v12+ comparisions this no longer will/should be needed. For which then best a new minor (e.g. 1.03.x) version of jcrdiff can be created.
