Avoid "file does not contain a valid yaml hash" warning for puppetserver

[XMol]

For every catalog build with this module included, the puppetserver logs a warning with...

Puppet /etc/puppetlabs/code/environments/production/modules/augeas/data/common.yaml: file does not contain a valid yaml hash

Please change the content of data/common.yaml to something that evaluates into a Hash, e.g. just {}, which meets this requirement, as opposed to ---.

• Puppet version: 5.5.22
• Module version: 1.9.0

This might be an inherent problem with our Hiera data_hash setting (lookup_key), but data_hash sounds like it expects a YAML mapping, too.

We have the same issue since we upgraded to the latest version.

• Puppet version: 6.21.1
• Module version: 1.9.0

This should be fixed in #85

Thank you!
