Has a bug in this commit when open Subscription settings:
Event settings already in Subscription settings - GSM call settings

PS2: This setting is added for non-world GSM phones only.
     Move this logic into the block that only gets executed for this case.
PS3: * Fix Event Notificatons for World Phone use case.
     * Don't call remove optional twice for msim.
