Allow naming of verify test.

Current tests are (anonymous). This patch allows passing test name when
setting up the verify.

Before

  TAP version 13
  # (anonymous)
  ok 1 should be equal

  1..1
  # tests 1
  # pass  1

  # ok

After

  TAP version 13
  # beep boop
  ok 1 should be equal

  1..1
  # tests 1
  # pass  1

  # ok
