Incorrect yaml formatting

Dapperdata incorrectly fixes yaml files when a list is at the root level of a document

    name: Trim Trailing Whitespace

this appears to be related to yaml.indent(mapping=2, sequence=4, offset=2), if i change it to yaml.indent(mapping=2, sequence=2, offset=0) dapperdata (ruamel) correctly formats the above yaml. Looking into ruamel to see if there is an open bug.

Applying the (mapping=2, sequence=2, offset=0) breaks other tests, so that's not going to work. I'm going to wait on the upstream library to see if they make any fixes.
