[1491] copy default named-set data to local when editing

if a child member is set, and the named-set data is default, it would 'lose' the other default values if it wasn't copied to local. For succesful operations this wouldn't be a problem (as this only happens 'locally' in bindctl), but it can cause problems when updates fail due to mistyped data
