[web][native] Reset the state iff current user ID changes

Summary:
We don't need to clear the state if the ID remains the same - it means that user-specific data can be still used. Every time the ID changes we have to clear the user specific data - it is safer to do that regardless of the action reduced.

In this approach we're reducing currentUserInfo twice - the reason is explained in code comments.

Depends on D11532

Test Plan: Checked if the state is cleared after logging out.
