`onyo new` errors when using default `empty` template

[aqw]

When using the empty template, onyo new errors.

❱ onyo new --edit --directory spaces/place
ERROR: Invalid item in YAML document (/home/aqw/git/inm7/inventory/.onyo/templates/empty).

This is also the case when explicitly declaring the empty template.

It seems to be correctly formatted:

❱ cat .onyo/templates/empty
---

Version:

❱ onyo --version
onyo 0.5.1.dev245+g3fae054
