- Reflect the actual return value returned by the implementation in the
the interface. E.g. IUser|bool -> IUser|false
- Remove $hasLoggedIn parameter from private countUser implementation.
Replace the two call with the equivalent countSeenUser
- getBackend is nuallable, add this to the interface
- Use backend interface to make psalm happy about call to undefined
methods. Also helps with getting rid at some point of the old
implementActions
