Applying Scrutinizer Suggestions

I do not understand one suggestion, and I believe one is wrong.
I will add comments to my ticket once this is pushed.

One that I can discuss up front
PhpWord/Style/Paragraph indicates that Indentation must be of type
   \PhpOffice\PhpWord\Style\Indentation, but it can also be null.
   My test for instanceof ... is one of the Scrutinizer reports.
   I did not change PhpWord/Style/Paragraph, but this commit does so
   by updating @var for indentation.
