Fixes a race allowing transactions to be rotate away before applied

The problem was that there was a window after appending the transaction to
the log and before marking that transaction as committed where a log
rotation could come in and rotate the log. The rotator would not wait for
the transaction(s) that had just been appended, and potentially also
forced since it hadn't even been marked as committed yet.
So a crash right after or at least before the changes of such
transactions would have been applied and fully forced to the store would
be lost since the transaction describing those changes would not be
recovered.

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;

|            Slice |    1 |        0 |             |         {  AUTOINT0} |
|           Filter |    1 |        1 |             | hasLabel(m:topic(0)) |

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

When using unnamed identifiers instead of just removing all unnamed identifiers
leading to outputs like `NOT( == )`, we now output `NOT(anon[22] == anon[42])`.

Fix collision on item properties and node-id / rel type in GraSS.

Ignore that we don't know about the previous transaction, because the case here is that we just restored a backup that doesn't have the log, and that's fine.
