Reopen message filestream before retrying w/o SmartReply/Forward

* If the original message being replied to/forwarded has been
  deleted before the reply/forward is sent, we get a 150 status
  from EAS 14 and retry without the "smart" feature
* However, we weren't resetting the message file stream before
  the retry, causing the send to fail
* Trivial fix, moving the file stream opening into the loop
