[React native] [Teams] Members counter is not updated when user joins/leaves team

[Dasha1990]

Device: Samsung S4 note 6.0.1, iPhone 6 11.4

Steps to reproduce:

1. login to the app
2. Join any team
3. Check response
   http://52.143.138.160:50000/api/v1/me/team is sent
   with team id
   {
   "team": "3b61c81a-2b8e-11e8-b467-0ed5f89f718r"
   }
   and team entity in response is:
   "teamInfo": {
   "name": "GSMA",
   "teamDescription": "Are you an employee or friend of GSMA. Join this team and help to make the change towards a cleaner and healthier world.",
   "image": "https://ucarecdn.com/82023a51-d50a-4f2f-aa0f-7e3a938de06b/Blueish.png",
   "nationalTeam": true,
   "createdAt": "2018-06-27T13:38:11.882Z",
   "id": "3b61c81a-2b8e-11e8-b467-0ed5f89f718r",
   "members": 0,
   "trashpoints": 0,
   "lastTrashpoints": [],
   "groupCount": {}
   }

Actual result: team is returned in users profile as his team but member counter is not updated + trashpoints which user creats aren't added to team statistics + user can join any other team without leaving current one and teams are just overwritten in his profile http://take.ms/uu8zU

Expected result: user becomes team member and member counter increased by 1

Partly a duplicate of #287
it's unclear if the fixes were moved over, they don't seem to be merged to master yet.

got it. as I understand now this works fine on the prod so we would need to find and add this functionality to server side

[Dasha1990]

now its blocking us from checking full flow, cause we can't correctly join team, see members list, see team stats

Surely that's a different or higher level bug?

I guess this issue with join also caused all other stuff and server logic will work when users will join team correctly (as I understand it is only backend part and apps can't really affect it)
