    loginDialog: Don't call _loginScreenSessionActivated() when not required
    
    We are calling _loginScreenSessionActivated() even in cases where this is
    not required. For example, there are cases where the Active property is
    already `true` and properties like `IdleHint`, `IdleSinceHint` and
    `IdleSinceHintMonotonic` change. In this cases _loginScreenSessionActivated()
    is called and will reset the authPrompt when not necessary.
