keter without arguments prints misleading error message

[schoettl]

I compiled keter from source, version 1.4.3.2.

When running keter, I get the message

keter: Usage: keter <config file>
CallStack (from HasCallStack):
  error, called at main/keter.hs:26:5 in main:Main

So I called it like /opt/keter/bin/keter /opt/keter/etc/keter-config.yaml as statet in the README.

I don't know what happens if the config file exists. But if it doesn't, keter creates a directory called /opt/keter/etc/keter-config.yaml/ and puts the directory structure that should be in /opt/keter/ into this directory. That is, the etc/, log/, incoming/, ... folders are all in the keter-config.yaml/ directory.

It took me a while until I found the log files to debug ^^
Apparently I have to call keter /opt/keter instead.
