elemental-operator is silent if it cannot find the local machineRegistration file

If you run elemental-operator register /path/without/yaml all you get in the log is

Operator version 0.3.0, commit 90791e4, commit date git20220720

and it exits.

I would expect a warning (error ?) saying something like

Warning: No userdata.yaml found at /path/without/yaml

Running elemental-operator register /non/existant/path results in a memfault

Running either with --debug doesn't change the output.
