Certificate validation is bypassed on missing key

[aw]

Certificate validation will return an error message (http-msg 400) if no public/private key is sent, but will continue processing and still end up calling (certs-update), because (http-msg 400) isn't final.

Luckily the backend scripts in Jidoteki Admin have safeguards and will return 1 (and fail) if there's no public/private key file, but this should still be corrected.

The bug can be found in the code here. It's a bit subtle, but essentially on L50 after calling (http-msg 400), the next condition (if Private.. will be called. Doh. Not what we expected.. 🤕 🌴

[aw]

Fixed.
