Dynamically generate proper RDF of repeatable literals

[jgreben]

When removing a literal value from a repeatable field, RDF reducer should properly remove values and re-generate the RDF. Currently, after adding multiple literals (e.g. "A", "B", and "C") when you remove a value (by clicking the "x"), the RDF generation remains the same:

{
  "@context": {
    "rdf": "http://www.w3.org/1999/02/22-rdf-syntax-ns#",
    "rdfs": "http://www.w3.org/2000/01/rdf-schema#",
    "xsd": "http://www.w3.org/2001/XMLSchema#",
    "bf": "http://id.loc.gov/ontologies/bibframe/",
    "bflc": "http://id.loc.gov/ontologies/bflc/",
    "madsrdf": "http://www.loc.gov/mads/rdf/v1#",
    "pmo": "http://performedmusicontology.org/ontology/"
  },
  "@graph": [
    {
      "@id": "_:n3-0",
      "@type": "http://id.loc.gov/ontologies/bibframe/Instance",
      "http://id.loc.gov/ontologies/bibframe/issuance": {
        "@id": "http://id.loc.gov/vocabulary/issuance/mono"
      },
      "http://id.loc.gov/ontologies/bibframe/carrier": {
        "@id": "http://id.loc.gov/vocabulary/carriers/nc"
      },
      "http://id.loc.gov/ontologies/bibframe/responsibilityStatement": [
        "A",
        "B",
        "C"
      ]
    },
    {
      "@id": "http://id.loc.gov/vocabulary/issuance/mono",
      "@type": "http://id.loc.gov/ontologies/bibframe/issuance",
      "rdfs:label": "single unit"
    },
    {
      "@id": "http://id.loc.gov/vocabulary/carriers/nc",
      "@type": "http://id.loc.gov/ontologies/bibframe/carrier",
      "rdfs:label": "volume"
    }
  ]
}

Note: Adding values works fine.
