Apply CLI-supplied defaults for incoming mail only to new issues not replies
Replying to an issue mail used to ignore default parameters passed to the mail-handling rake task, or to be precise did only care for other parameters than those we pass on the command line. The refactorings in r4394 changed that though, and now replies to "issue mails" re-apply the defaults passed on the CLI, which I don't think is something that should happen.
- Create a new issue, say in the tracker "Bug"
- Write a reply to the mail you just got for that issue, the mail gets imported with:
rake redmine:email:receive_imap … tracker=Support
- The tracker of the issue gets changed to "Support"
