Use patches on tests

[c-martinez]

The test_sparql_transformer test, relies on response from dbpedia:

grlc/tests/test_gquery.py

Lines 208 to 219 in f5664e3

	def test_sparql_transformer(self):
	rq, _ = self.loader.getTextForName('test-json')
	endpoint, _ = gquery.guess_endpoint_uri(rq, self.loader)
	self.assertEqual('http://dbpedia.org/sparql', endpoint, 'Should match endpoint in test-json.json')
	resp, status, headers = utils.dispatchSPARQLQuery(rq, self.loader, content=None, requestArgs={},
	acceptHeader='application/json',
	requestUrl='http://', formData={})
	self.assertEqual(status, 200)
	self.assertIsInstance(resp, list)
	self.assertIn('id', resp[0])

This means that if you are not connected to the internet, it is not possible to run this test. One way to work around this is to use @patch (as done in test_get_enumeration test) to mock the http request.

@pasqLisena -- could you possibly have a look at this test?
