The type of an array nested beneath an array is incorrectly determined to be the type of the array's contents

[wilkinsona]

Specifically, this test will fail as the resolved type is JsonFieldType.NUMBER:

assertThat(
        this.fieldTypeResolver.resolveFieldType("a[].b[]",
                createPayload("{\"a\": [{\"b\": [ 1, 2 ]}]}")),
        equalTo(JsonFieldType.ARRAY));
