DumpLogicalLog: Output format version.
Fixed issue with prematurely exhausted iterator.

By exhausting the iterator on initialization, some queries lead to a lot
of unnecessary dbhits, e.g.
````
profile MATCH (n:topic)-[r]->(m:topic) return n,r,m limit 1;

+------------------+------+----------+-------------+----------------------+
|         Operator | Rows |   DbHits | Identifiers |                Other |
+------------------+------+----------+-------------+----------------------+
|            Slice |    1 |        0 |             |         {  AUTOINT0} |
|           Filter |    1 |        1 |             | hasLabel(m:topic(0)) |
| TraversalMatcher |    1 | 11292978 |             |              m, r, m |

should ideally only touch a small portion of the graph but ends up touching something like
50% instead. This fix I believe fix this.
