Bug Report

Reproducible in:

slackclient version: 2.2.1

python version: 3.7.2

OS version(s): Ubuntu 18.04.3 LTS x86_64 (in VirtualBox 6.0.10 for Windows 10)

Steps to reproduce:

import slack

client = slack.WebClient(API_TOKEN)
for page in client.users_list(limit=1):    # small limit to impose multiple pages
    for member in page['members']:
        print(member['name'])

Expected result:

Output all user names.

Actual result:

slackbot
Traceback (most recent call last):
  File "foo.py", line 4, in <module>
    for page in client.users_list(limit=1):
  File "/home/foo/.pyenv/versions/3.7.2/lib/python3.7/site-packages/slack/web/slack_response.py", line 139, in __next__
    req_args=self.req_args,
  File "/home/foo/.pyenv/versions/3.7.2/lib/python3.7/asyncio/base_events.py", line 584, in run_until_complete
    return future.result()
  File "/home/foo/.pyenv/versions/3.7.2/lib/python3.7/site-packages/slack/web/base_client.py", line 258, in _request
    auth=req_args.pop("auth"),
KeyError: 'auth'

The first user (slackbot) in the first page is fetched correctly, but slackclient fails to go on to the second page.
