test: revert non-intentional changes introduced in eb4cf465

eb4cf465 introduces changes which weren't part of the submitted
patch (id:"87liwlip2j.fsf@gmail.com"), presumably made during
resolving merge conflicts.

The first one causes the title of a test to be printed a second time,
in place of the correct title:

  PASS   Message with .. in Message-Id:
  PASS   Message with .. in Message-Id:

instead of:

  PASS   Message with .. in Message-Id:
  PASS   Sending a message via (fake) SMTP

The second one is simply the insertion of a line break, so no harm there.

This commit reverts both changes, as they were clearly accidental.
