Description of the bug

JSON request body whose root starts with an array fails to match with JsonPath as matcher.

Steps to reproduce the issue

Any http request with the following body
https://jsonplaceholder.typicode.com/posts

and the simulation file containing the following matcher

        "body" : [ {
          "matcher" : "JsonPath",
          "value" : "$[0]"
        } ]

Edit: It also occurs with JsonPartial

        "body" : [ {
          "matcher" : "jsonpartial",
          "value" : "{\"userId\": 1}"
        } ]

Observed result

Hoverfly error messages seen (If none, say none)

Failed to unmarshal body to JSON: json: cannot unmarshal array into Go value of type map[string]interface {}

If possible, add screenshots to help explain your problem

Expected result
