[BUG] unexpected result parsing in GOpt

**Describe the bug**
A clear and concise description of what the bug is.

Run the query on modern graph, and the result is not as expected, seems due to a wrong deduced type:
```
gremlin> g.V().hasLabel("person").both("1..3","knows").with('RESULT_OPT', 'ALL_V').elementMap("age")
cannot parse label value=29 from expected type=[VertexLabel(software), VertexLabel(person)], expected ids are [1, 0]
Type ':help' or ':h' for help.
```
In this case, the results contains value of "age" as 29, while, somehow, the result parser regard this as a VertexLabel, and try to convert 29 back to the label, which then throws out the error.
