Output RDFa markup for type + title in taxonomy term reference and entity reference formatters

Removed

    // Taxonomy terms triples.
    // Term 1.
    $expected_value = [
      'type' => 'uri',
      'value' => 'http://www.w3.org/2004/02/skos/core#Concept',
    ];
    // @todo Enable with https://www.drupal.org/node/2072791.
    // $this->assertTrue($graph->hasProperty($taxonomy_term_1_uri, 'http://www.w3.org/1999/02/22-rdf-syntax-ns#type', $expected_value), 'Taxonomy term type found in RDF output (skos:Concept).');
    $expected_value = [
      'type' => 'literal',
      'value' => $term1->getName(),
    ];
    // $this->assertTrue($graph->hasProperty($taxonomy_term_1_uri, 'http://www.w3.org/2000/01/rdf-schema#label', $expected_value), 'Taxonomy term name found in RDF output (rdfs:label).');
    // Term 2.
    $expected_value = [

      'value' => 'http://www.w3.org/2004/02/skos/core#Concept',
    ];

Which can be added back with this issue but not going to keep this in the main repo if I can help it.
