Subject: [PATCH] [BUGFIX] Avoid xargs error for empty project (#370)

The `xargs` shell command will throw an error if find will return an empty result.
Adding `-r` will prevent this error.

Example:
A project has no yml files.
- Before: The yaml-linting fails.
- With that patch: The yaml-linting succeed.
