Fix tests

* Add `fixtures.yml`.
* Add `default_module_facts.yml` with `staging_http_get` fact.
* Rubocop fixes in `spec/classes/example_spec.rb`.
* Remove completely broken tests.

Looks like there aren't really any tests and
`spec/classes/example_spec.rb` is just boilerplate/skeleton.

For instance there is no `config.pp` manifest, so
```ruby
it { is_expected.to contain_class('splunk::config') }
```
was never going to pass!
