Describe the bug
group_member using deprecated group rest api call, which causes missing users in our instance

To Reproduce
I do see different results from /rest/api/2/group and /rest/api/2/group/member api calls for same group, where former one is missing some users. but I couldn't figure out what is causing this issue.

One thing to notice is on UI: System -> User -> on search group and active should match with rest api call results.

Code block
Get group api is DEPRECATED GET /rest/api/2/group```
New Api: GET /rest/api/2/group/member

1. Any additional steps or considerations that happen before or after.

**Expected behavior**
 UI: System -> User -> on search group and active should match with rest api call results.
**Stack Trace**

A code block with the any trace messages.

**Version Information**
Python Interpreter: <Python 2.7.10>
jira-python: <jira==1.0.8>
OS: <IOS version 10.14.4>

I've run into this lately, now it's not just deprecated, but has been removed.
