🐛 Prevent client from prepending --app for network commands

The dokku client auto-detects the app name from the git remote
and prepends `--app <name>` to all SSH commands not explicitly
excluded. Network commands like `network:create` take a network
name (not an app name) as their first argument, so the injected
app name was being used as the network name instead.
