Removed the -no auth attempts- from the triggers because of lots of FP

[aseques]

According to dovecot's wiki http://wiki2.dovecot.org/WhyDoesItNotWork

Aborted login (no auth attempts) means that the client isn't even attempting to log in. Most likely you have disable_plaintext_auth=yes (default) and the client isn't configured to use SSL/TLS (or you've also set ssl=no).

Looking on our logs, I found plenty of legitimate clients facing this error, and found on the internet reports for many mail clients (thunderbird, kmail, outlook, ..), just have a look at "no auth attempts" at google. Most of the times is mail client fault

Hence I disabled this from the regexp and adjusted both the sample logs and the code.

Actually grouping the test cases you've removed and changing the "match" to "false" in failJSON would be good so we don't accidentally cover this again.

I'm ok with this change. Wouldn't mind someone else confirming it.

👍 I've noticed that when connections drop from bad mobile phone signal this can trip...

thank you. I've merged this in #601 with additional samples from the mailing list.
