The commit message was not immediately clear for me.

If one sets X, Y as the values of "Recipient(s)", and "Additional
Recipients(s)" in a Sendmail notification target, and then modifies it
so that either X=`` or Y=``, /etc/pve/notifications.cfg will incorrectly
contain the old values instead of removing the corresponding line:

    sendmail: test
            mailto Y
            mailto-user X

Tested setting both mailto and mailto-user to `` from non-nil values and
switching their values around. The patch fixes this as far as my testing
went.
