Some users reported an error where the SDK said that the content type of a response was application/json, application/json; charset=utf8. It is invalid to have multiple Content-Type values in a response and the LaunchDarkly service does not do this, but an improperly configured proxy/gateway might add such a header. Now the SDK will tolerate a value like this as long as it starts with application/json.
Fixed incorrect usage of Object.hasOwnProperty which could have caused an error if a feature flag had hasOwnProperty as its flag key.
