This override was accidentally introduced by commit de6c331.
The Debian postinst script will ask for and generate a config with the
address set. This should not be overriden by what is set in the default
config and is thus a deviation from the standard docs.
* The Debian part will be generated and managed by Debconf and configure
homeserver name, address and port
* The local part will just be a config file that shows the other
configuration options
Added the address configuration and moved the config generation
from the config to the postinst script.
