Validate that upgrading existing repository to 11.0 wrt translations, documents can still be found by the translated name

Most likely it will just work, but to be sure, we need to validate that when a groovy script runs that replaces the hippo:translation node(s) below a handle to 'hippo:name' property on the handle, that we can still search the documents on the 'hippo:name' value. During the testing, the actual documents are not allowed to be touched (thus only the move of hippo:translation to hippo:handle). If the documents are touched, the index will be re-created for sure

For a clean repository this will work for sure (unit tests). For an upgraded repository, this most likely also works (via the JR FieldNames.AGGREGATED_NODE_UUID logic), but we need to confirm this. It is a tricky area
