netcardconfig: sed command resets WPASECRET

On second invocation the password might end up being empty.
Then there's no chance to get a working netcardconfig
again without manually editing /etc/network/interfaces,
as the ugly awk command line can not parse the file
any longer with an incomplete wpa-psk line.
