Prepended dot in TXT-records

[kaspergrubbe]

# certbot
s.entry('CNAME', '_acme-challenge.nav.billetto.com', 'yaOgKnUdbBSL48lsyoaPk0OusZualdls8rZvUVEDnHw', 360)

Becomes:

[kaspergrubbe]

I didn't notice that I added a CNAME and not a TXT record. But it allowed me to test another use-case:

Create:

s.entry('CNAME', '_acme-challenge.nav.billetto.com', 'yaOgKnUdbBSL48lsyoaPk0OusZualdls8rZvUVEDnHw', 360)

Delete it, and run this:

# s.entry('CNAME', '_acme-challenge.nav.billetto.com', 'yaOgKnUdbBSL48lsyoaPk0OusZualdls8rZvUVEDnHw', 360)
s.entry('TXT', "_acme-challenge.nav.billetto.com", %q{"yaOgKnUdbBSL48lsyoaPk0OusZualdls8rZvUVEDnHw"}, 360)

Now this will appear:
