• POULPE-268 - add user to respective group while banning. In order to show this, we need to leave only 500 users in our database, because while opening a window with group members, it will load all 20K we have atm.

  1. go to the user groups page
  2. open banned users list members
  3. select some not banned user and show that it's no reference from user to the banned group in DB
  4. add it to the list and save
  5. show that BAN_REASON field for the user in DB have NULL value
  6. show that new reference was added from the user to the banned group
  7. same logic for the removing user from banned group
