Fix carrier config option not hidden on a CDMA phone

 * The option is added twice, from GsmUmtsOptions and CdmaOptions, and
   GsmUmtsOptions unconditionally adds it if current phone type is not
   GSM. This is obviously wrong, and on a CDMA phone the option persists
   even if it's disabled from CarrierConfig. Once a user selects it,
   phone app will crash.
 * To fix it, reverse the initial value of the boolean, so that
   GsmUmtsOptions won't add the option if current phone type is not GSM.
