t9000-addresses.sh: unexpected pases

Hi Matthieu,

I have started seeing unexpected passes in this test (am I the only one?) on the next and pu branch, which seems to be caused by commit e3fdbcc8 ("parse_mailboxes: accept extra text after <...> address", 13-10-2016). Thus:

  $ tail -15 ntest-out
  [15:17:44]
  All tests successful.

  $ 

I have not even looked, but I suspect that it simply requires a change from expect_fail to expect_success, since your commit has 'fixed' these tests ... would you mind taking a quick look?

Thanks!
