Subject: #1955 - Make unit test photos unique. - Added
 test::random_unique_photo and test::random_unique_photo_unsaved to uniquify
 test photos. - Uniquified the black dot of test.jpg by coloring it with the
 six-digit hex code already used to name the random photos (e.g.
 "name_a48801.jpg"). - Modified four tests in Item_Model_Test that check photo
 file contents to use new functions to guarantee uniqueness.
