get_users_in_list fails due to Iterable API returning invalid json

[titanium-cranium]

Hi there!

Having a similar problem to issue 2 with the get_users_in_list method.

The Iterable API returns text/plain list of email addresses separated by line feeds from the /api/lists/getUsers endpoint. As a result, the normal base api_call crashes in the same manner as was described for issue2, trying to parse JSON when it's not formatted properly.

After a bit of playing around using requests to get the data, I found the response could be parsed into an array using r.decode("utf-8").splitlines()

I'd propose the get_users_in_list endpoint simply use the export_data_api instead of api_call so that it can be used to get the response object without the .json() call.

Thoughts?

Cheers,

Brendan
