Resolves #916: Partially reverted #799.

- Reviewed the code and the semantics of processAllModules, groupId, artifactId, oldVersion params
- Dropped support for partially interpolating the properties to be matched with groupId:artifactId:oldVersion
- Matching occurs always unless *processAllModules* is set
- If *processAllModules* is not set, *oldVersion* will be respected
- Included an additional test case from #916 testing child version
