Combine @fold and @recurse on the same edge

[obi1kenobi]

For example, on the "numbers" schema:

query {
    Four {
        predecessor @fold @recurse(depth: 5) {
            value @output
        }
    }
}

This should return:

{
    "value": [4, 3, 2, 1, 0]
}

Recall that @recurse always starts with "depth 0" i.e. the current vertex before the edge is traversed. This is why 4 is in the output list.
