SensitivePn: Take into account multiple SIMs for sensitive numbers

* Instead of only checking the current or default MCC to hide a number,
  see if any of the connected networks would hide a number
* This makes sure that e.g. for multiple sims (e.g. living next to the
  country border, having one sim for each country) and accidentially using
  the wrong sim for a call, the number would still get hidden
