Use new usage feedback API in phone app / strequent

Basiaclly two changes included:

- Let CallLog use new data usage feedback API, so that
  ContactsProvider2 is able to figure out what type of contact
  method is used when a person is contacted.
- introduce phone_only parameter for strequent uri, which enables
  Contacts app to obtain a contact list for recently phone-called
  contacts.

markAsContacted() isn't used anymore, as nhe new API takes care of
old counters (TIMES_CONTACTED/LAST_TIME_CONTACTED) too.
