[Jetpack Focus] Avoid that login is triggered when user logs out of JP

[RenanLukas]

With the current implementation in SharedLoginResolver (that will be renamed to LocalMigrationOrchestrator) if the user is already logged in to JP and logs out manually, they will be logged in automatically again if WP app is logged in. We should avoid that automatic login is triggered when user logs out of JP manually.
