assert.partialDeepStrictEqual now also handled error properties as expected. On top of that, the main implementation also handles non-string `name` and `message` properties and the comparison is a tad faster by removing duplicated comparison steps. As a drive-by fix this also cleans up some code by abstracting code and renaming variables for clarity.
