JSON_PATHS support

[spicy-sauce]

Hi,
You've added such a support a while ago, but it seems like the JSON_PATHS is wrong, as it currently contains:
JSON_PATHS: ['tailored_audience_memberships']

This URL does not exist in Twitter Ad API (correct me if I'm wrong).
On the other hand, this endpoint should be sent in JSON:
accounts/:account_id/tailored_audiences/:tailored_audience_id/users

I also think that the condition in line 66 in twitter_ads.js won't meet:
if (constants.JSON_PATHS.indexOf(url) > -1 && ['post', 'put'].indexOf(type) > -1) {
Probably should change to:
if (url.indexOf(constants.JSON_PATHS) > -1 && ['post', 'put'].indexOf(type) > -1) {

Please, advise.

Thanks!
