Don't allow other records types when there is a CNAME for a record #2

PowerDNS seems to not have a problem with this but it breaks transfer from BIND. We should do something on the UI when the is both a CNAME for a record and anything other (A/AAAA)

Suppose a zone managed by PowerDNS contains these two records:

koko.grnet.gr.      3600    IN      CNAME      something.grnet.gr.
koko.grnet.gr.      3600   IN       MX      200 somemx.grnet.gr.

bind9 will fail to correctly transfer said zone like this:
