Update `JacksonTester` so that the JsonPath instance is explicitly configured with both a `JacksonJsonProvider` and a `JacksonMappingProvider`. Prior to this commit, the handling of special characters was not symmetrical between the serialization (handled via the JacksonTester) and the parsing (handled via JsonPath) due to the fact that JsonPath used `SimpleJson` as its parser.
