Make user business logic reusable (#1114)

- Refactor user business logic from `user.service` into `user.domain`
  Make user business logic reusable by using `user.domain` from other services than `user.service`

- Add `jest-when` lib to make testing easier and use it in `userService`
  Using when helps from coupling tests to order of mock implementations execution

- Move all user business logic from user-repository to user.service

- Fix user.service tests not awaiting promises leaking state between tests

- Presentation logic for `getUserProfileImage` moved from UserService to UserController

- Fix `user.e2e` test logic. Pending fixing the configuration of the test itself
