To Reproduce

1. Set server side cookie A=1 on XHR call (server shows cookie is sent)
2. Set another server side cookie A=2 on XHR call (server shows cookie is sent with any subsequent call)
3. immediately close app
4. reopen app server shows, that cookie value A=1 is sent instead of A=2

Expected behaviour
Persistence of cookie is done right after receiving the value.

Actual behaviour
Received Cookie value is not immediately persisted.
