[lib][web][native] Simplify logout call

Summary: Now that actions are wrapped in hooks we can select data in them. This simplfies the calling code and reduces repetition.

Test Plan: Checked that it is possible to log out and back in with no errors showing up. Checked that invalidSessionDowngrade works correctly (by loggin out and back in before logoutActionTypes.success was dispatched)
