bug(json): recursive deletion does not delete all the fields

[romange]

To reproduce:

> "JSON.SET" "doc1" "." "{\"a\": 1, \"nested\": {\"a\": 2, \"b\": 3}}"
>"JSON.DEL" "doc1" "$..a"
1
> "JSON.GET" "doc1" $
"[{\"nested\":{\"a\":2,\"b\":3}}]"

expected:

>"JSON.DEL" "doc1" "$..a"
2
> "JSON.GET" "doc1" $
"[{\"nested\":{\"b\":3}}]"

[romange]

"JSON.SET" "doc2" "$" "{\"a\": {\"a\": 2, \"b\": 3}, \"b\": [\"a\", \"b\"], \"nested\": {\"b\": [true, \"a\", \"b\"]}}"
"JSON.DEL" "doc2" "$..a"

return 2 but is expected 1.
