Rename function in PathOpsExtendedTest which takes strings.

A few methods in PathOpsExtendedTest were changed to write to SkStrings
instead of SkStreams. However, the names of these functions confusingly
still have "Stream" in their names. This CL is just a static function
rename and some small clean-up.
