[evolution-data-server] Added test case showing photo data stored as uris.

commit d6f0b79e0dc54777a03cd530661e3141724ea0fb

    Added test case showing photo data stored as uris.
    
    The test asserts:
      o binary inlined photos added to the EBook come out
        as uris in the EBookView signals
      o that it is still possible to use an external uri that the
        addressbook does not recognize at which point the addressbook
        is simply expected to store the provided URI string without
        any extra management (the test does this, however it only
        asserts that a uri is indeed returned).
      o When sharing an addressbook owned uri fetched from one contact
        and assigning it to the next contact, the second contact's uri
        is still accessible on disk after deleting the first contact.
