ContactItem improvements (#1324)

* ContactRepository: try to deduplicate phoneNumbers in a smart way

* AndroidManifest: use CALL_PHONE permission to allow for making phone calls

* Implement CallOnTap with contact results

- contact activities that require permissions we do not have are not
  listed
- add CallOnTap setting for phone number results on search behind
  contacts settings

* utilize PhoneNumberUtils

* navroute settings/search/contacts

* queryIntentActivities -> resolveActivity

* localization

* Code formatting

* Wrap contact search settings in preference category
