TUN-7404: Default configuration version set to -1

We need to set the default configuration to -1 to accommodate local
to remote configuration migrations that will set the configuration
version to 0. This make's sure to override the local configuration
with the new remote configuration when sent as it does a check against
the local current configuration version.
