Fix regression with editing me profile

Use Profile.CONTENT_RAW_CONTACTS_URI in PickRawContactLoader
if we're loading the me profile.
Changed rendering accounts attribution to be consistent with
the duplicates view.
  * Me profile -> "My local profile"
  * Focus Google account -> account name
  * All others -> account type display string (Google+, LinkedIn etc.)

Test:
Edit me-profile with G+ account attached
Edit me-profile without G+ account
Edit linked contact with device raw contacts
Edit linked contact with SIM raw contacts
Edit linked contact with Samsung raw contact
