patchbomb: respect --in-reply-to for all mails if no intro message is sent

Before this change, the thread hierarchy looked like this:

PARENT
  PATCH1/x
    PATCH2/x
    PATCH3/x
    ...

Now it is:

PARENT
  PATCH1/x
  PATCH2/x
  PATCH3/x
  ...

With an introductory message the behaviour is unchanged:

PARENT
  INTRO
    PATCH1/x
    PATCH2/x
    PATCH3/x
    ...
