 When adding a new zone we see this:

 {{{
 > config add Zonemgr/secondary_zones
 > config show Zonemgr/secondary_zones
 Zonemgr/secondary_zones[0]/class        "IN"    string  (modified)
 Zonemgr/secondary_zones[0]/name "time-travellers.nl.eu.org"     string
 (modified)
 Zonemgr/secondary_zones[1]/class        "IN"    string  (modified)
 Zonemgr/secondary_zones[1]/name "home.time-travellers.org"      string
 (modified)
 Zonemgr/secondary_zones[2]/class        "IN"    string  (default)
 Zonemgr/secondary_zones[2]/name ""      string  (default)
 > config set Zonemgr/secondary_zones[2]/name "example.com"
 > config commit
 Error: 'class'
 Configuration not committed
 > config set Zonemgr/secondary_zones[2]/class "IN"
 > config commit
 >
 }}}

 We should not have to set the class if we use the default.
