test fail feature: newline formatting and failed mail to root

[markstos]

I believe in the test mail, echo -e should be used for the newlines to be parsed properly.

Also, the test fail failed to go out through SES because it objected to the mail to root.

I guess that failed because I have msmtp_alias_root set up, so the mail is attempted to be forwarded through the smtp server, but the email address was left as only root, I'm not sure which component is at fault there, but I would just remove root as one of the test addresses, since msmtp is all about sending remote mail.

I believe the mail to "root" failed due to #14
