send-email: fix non-threaded mails
After commit3e0c4ff(send-email: respect in-reply-to regardless of threading, 2009-03-01) the variable $thread was only used for prompting for an "In-Reply-To", but not for controlling whether the "In-Reply-To" and "References" fields should be written into the email. Thus these fields were always used beginning with the second mail and it was not possible to produce non-threaded mails anymore. However, a later commit15da108("send-email: 'References:' should only reference what is sent", 2009-04-13) introduced a regression with the side effect to make non-threaded mails possible again, but only when --no-chain-reply-to was used.
