Description: utils: drop useless g_file_test() call
 canonicalize_file_name() returns NULL if file doesn't
 exist, so no need to check file existence with
 g_file_test().

 Without this patch calls to this function (as in the
 test-generated tests) will fail on glib2.0 v2.53+ 
 due to a NULL check introduced in g_file_test. The
 NULL check introduction was tracked at:
