[libvirt] [PATCHv3 22/36] tests: virstoragetest: Fix output when hitting errors

[Peter Krempa]

When the test is failing but the debug output isn't enabled the
resulting line would look ugly like and would not contain the actual
difference.

TEST: virstoragetest
      .................chain member 1!chain member 1!chain member 1!

Store the member index in the actual checked string to hide this problem
