Update to Yard >= 0.9.0

* Return a string from CodeObjects::HeaderObject#path

  A change in YARD::Serializers::FileSystemSerializer stopped
  calling `#to_s` on the the CodeObject passed, causing a NoMethodError
  for "+" missing Symbol (#path was just an alias to #name).

  Added minimal specs to cover only this case.

* Fixed some handler specs dealing with namespaces.

  A bug in the Yard c handler allowed namespacing to be determined
  without a proper parent RClass. See lsegal/yard#912

* There were some breaking changes to templates.
