Relationships created and deleted in batch-based transaction is not deleted

[versae]

Try this code as a test on neo4jrestclient.tests.test_transactions.TransactionsTestCase:

    def test_transaction_relationships_is_destroyed_after_transaction(self):
        a = self.gdb.nodes.create()
        b = self.gdb.nodes.create()
        with self.gdb.transaction(using_globals=False) as tx1:
            r10 = a.relationships.create("PREV_EVENT", b, tx=tx1)
            c = self.gdb.nodes.create(tx=tx1)
            c.relationships.create("PREV_EVENT", b, tx=tx1)
            a.relationships.create("PREV_EVENT", c, tx=tx1)
            r10.delete(tx=tx1)
        self.assertIsNone(r10)

The relationship r10 is still there after the transaction is executed.
