"online: true" field isn't removed from database when app minimizes

[anonym24]

1. Is the bug present in the demo Chat SDK project? yes, v5.0.16

2. What modifications have you made to the Chat SDK? none

3. Android Version: 21-30

4. Steps taken to reproduce the problem: open chat demo app, login, minimize (don't remove from history), check firebase, online status is shown for that user, it's only being deleted when app is removed from history

5. Expected result:
   "online: true" should have removed, or set to false

6. Actual result:
   "online: true" even after app was minimized

it works on old 5.0.0rc25 when app minimized

but on 5.0.1-5.0.16 online status is removed only when app is removed from history
