Path variable is missing from RETURN * output

RedisGraph 2.4.14, 2.8.11

For each of the following queries:

```
GRAPH.QUERY g "MATCH (c), (k), p = (c)-[*]-(k) RETURN *"
GRAPH.QUERY g "MATCH (c), (k) MATCH p = (c)-[*]-(k) RETURN *"
GRAPH.QUERY g "MATCH (c), (k) WITH c, k MATCH p = (c)-[*]-(k) RETURN *"
```

The output contains c and k.
Expected: c, k, and p.
