Failed to get followers, following and unfollowers counts

On Windows 10 running through PyCharm.

I'm trying to get my followers and unfollowers from my original account (pre InstaPy) but InstaPy is unable to find them.

I run the following code:

```
from instapy import InstaPy
from instapy import smart_run

def job():
# get an InstaPy session!
# set headless_browser=True to run InstaPy in the background
session = InstaPy(username=insta_username,
password=insta_password,
want_check_browser=False,
headless_browser=True,
disable_image_load=True)
with smart_run(session):
session.set_quota_supervisor(enabled=True,
sleep_after=["likes", "comments_d", "follows",
"unfollows", "server_calls_h"],
sleepyhead=True, stochastic_flow=True,
notify_me=True,
peak_likes_hourly=55,
peak_likes_daily=566,
peak_comments_hourly=33,
peak_comments_daily=182,
peak_follows_hourly=55,
peak_follows_daily=None,
peak_unfollows_hourly=22,
peak_unfollows_daily=333,
peak_server_calls_hourly=None,
peak_server_calls_daily=4700)

nonfollowers = session.pick_nonfollowers(
username="kevinjohnsrude",
store_locally=True,
live_match=True)
print(nonfollowers)

job()
```

Here's my output:

```

```

Start with relationship_tools.py in get_followers and get_nonfollowers, then trace the call from instapy.py through pick_nonfollowers. Reproduce the provided script and inspect the Selenium execute_script failures involving window.__additionalData and window._sharedData; done means follower and following counts are retrieved without the reported JavaScript exceptions.
