Src and dest node are not shown properly for non-directional matches: (a)-[r]-(b)

Given the following queries:

MATCH (n0:Note {id: 11})-[r:Links]->(n:Note {id:12}) RETURN ID(n0), r, ID(n);
-------------------------------------------------------------------------------
| n0._ID   | r                                                     | n._ID    |
-------------------------------------------------------------------------------
| 1:435121 | (1:435121)-{_LABEL: Links, _ID: 2:841305}->(1:435122) | 1:435122 |
-------------------------------------------------------------------------------

MATCH (n0:Note {id: 11})<-[r:Links]-(n:Note {id:12}) RETURN ID(n0), r, ID(n);
-------------------------------------------------------------------------------
| n0._ID   | r                                                     | n._ID    |
-------------------------------------------------------------------------------
| 1:435121 | (1:435122)-{_LABEL: Links, _ID: 2:841307}->(1:435121) | 1:435122 |
-------------------------------------------------------------------------------

MATCH (n0:Note {id: 11})-[r:Links]-(n:Note {id:12}) RETURN ID(n0), r, ID(n);
-------------------------------------------------------------------------------
| n0._ID   | r                                                     | n._ID    |
-------------------------------------------------------------------------------
| 1:435121 | (1:435121)-{_LABEL: Links, _ID: 2:841305}->(1:435122) | 1:435122 |
-------------------------------------------------------------------------------
| 1:435121 | (1:435121)-{_LABEL: Links, _ID: 2:841307}->(1:435122) | 1:435122 |
-------------------------------------------------------------------------------

The third query result is shown wrong. The IDs should be exchanged in the 2nd row.

Similarly, path is shown wrong too:

MATCH p=(n0:Note {id: 11})-[r:Links]-(n:Note {id:12}) RETURN properties(nodes(p), '_ID'), ID(n0), ID(n);
--------------------------------------------------
| PROPERTIES(NODES(p),_ID) | n0._ID   | n._ID    |
--------------------------------------------------
| [1:435121,1:435122]      | 1:435121 | 1:435122 |
| [1:435121,1:435122]      | 1:435121 | 1:435122 |
--------------------------------------------------

This should now be fixed in #3404
