issue 743 contacts.other search

[sosnovsky]

This PR adds search through email addresses which are not stored in user's Gmail contacts. It also needs additional auth scope https://www.googleapis.com/auth/contacts.other.readonly (currently it shows warning screen when user authenticates for the first time)

Tests (delete all except exactly one):
