Subject: [PATCH] ignore const expressions read by phpdocumentor

With the upcoming release, phpdocumentator will use the PhpStan docblock parser
to extract type information. This change ensure that constant expressions are
ignored when extracting types (as we did before when phpdocumentor failed to
extract the type) as we do not evaluate them inside the PhpDocExtractor.
