SPARQL targets : "double dot" error when the SPARQL string contains a final dot

[tfrancart]

target SPARQL query:

SELECT $this
WHERE {
  $this a <https://www.ica.org/standards/RiC/ontology#RecordSet> .
  $this <https://www.ica.org/standards/RiC/ontology#hasRecordSetType> <http://vocab.performing-arts.ch/rsfnd> .
}

generated datasource SPARQL query to populate list (note the double dot)

SELECT ?uri ?count (CONCAT(STR(?theLabel), ' (', STR(?count), ')') AS ?label)

      FILTER(isIRI(?uri))
      # range criteria
      ?uri a <https://www.ica.org/standards/RiC/ontology#RecordSet> .
 ?uri <https://www.ica.org/standards/RiC/ontology#hasRecordSetType> <http://vocab.performing-arts.ch/rsfnd> . .
    }
    GROUP BY ?uri
  }
  ?uri <https://www.ica.org/standards/RiC/ontology#name> ?theLabel .
  FILTER(lang(?theLabel) = "" || lang(?theLabel) = 'en')
  }
  ORDER BY UCASE(?theLabel)
  LIMIT 500
  }
}
ORDER BY UCASE(?label)

the SPARQL rewrite regex should take this into account. Right now, this means the SPARQL target definition MUST NOT use a final dot for the last criteria, e.g. in our example:

SELECT $this
WHERE {
  $this a <https://www.ica.org/standards/RiC/ontology#RecordSet> .
  $this <https://www.ica.org/standards/RiC/ontology#hasRecordSetType> <http://vocab.performing-arts.ch/rsfnd>
