Formatter / Full view missing/extra matching nodes

In #9000, we added a tentative fix for improving labels when translations contains labels with xpath context.

eg.
```xml
<element name="gmd:description" context="/gmd:MD_Metadata/gmd:identificationInfo/gmd:MD_DataIdentification/gmd:extent/gmd:EX_Extent/gmd:description">
    <label>Beschrijving temporele dekking</label>
    <description>temporele dekking van de data, gespecificeerd als een periode.</description>
  </element>
```

This was not working due to the formatter reading the editor config, find matching field/section to render using saxon `evaluate` function. One drawback is that when using this function, the returned node does not have its context (eg. `..` to get its parent). So the logic to get label based on xpath can't work.

To avoid this a check was made to retrieve the corresponding the original node in the document and `deep-equal` function was used for that. But we noticed some case not handled
* #9163 2 sections matching the xpath of the editor config (due to wrong usage of deep-equal)
* More than one node matching at different location in the document (eg. a DCAT-AP document with the same license in Catalog and Service will display the 2 license for the service).
* No matching element when using a section with a forEach attribute.

Note: In edit mode, unique ref in `gn:element` is used to retrieve
original node which is more reliable but can't be used in view mode.

Proposal is to find the original node using `deep-equal` and then checking using node xpath matching when the xpath does not make use of wildcard. If wildcard, then `evaluate` returned nodes are used (and may cause the label issue).
