[TINKERPOP-551] Neo4j multiple labels can not be queried individually - ASF JIRA

With TP3 M7, I can add multiple labels to Neo4j vertex:

gremlin> v = g.addVertex(label, 'test', 'wikibaseId', 'test')
==>v[3]
gremlin> v.addLabel('test2')
==>null
gremlin> v.labels()
==>test
==>test2

However, if I try a lookup by this label, it does not work:

gremlin> g.V().has(label, 'test2')
gremlin> g.V().has(label, 'test')
gremlin> g.V().has(label, 'test').hasNext()
==>false

This lookup works for nodes with single label, but not for nodes with multiple labels. This, however, works:

gremlin> g.cypher('MATCH (x:test2) RETURN x')
==>[x:v[3]]

So Neo4j query works fine, while TP3 one does not.
