Dear maintainer,

systemctl cat currently fails with the following assertion error, on inexistent
unit templates:

  $ systemctl cat ssh at .service
  Assertion 'name' failed at src/shared/dropin.c:143, function unit_file_find_dirs(). Aborting.
  [1]    670974 abort      systemctl cat ssh at .service


Existant templates and inexistent non-templated units seem unaffected:

  $ systemctl cat ssh.service    
  No files found for ssh.service.
  
  $ systemctl cat hostapd at .service
  # /lib/systemd/system/hostapd at .service
