[BUGFIX] Keep unmapped ?type parameter when using PageTypeDecorator

This change keeps the type parameter (e.g. ?type=13) even
if PageTypeDecorator is used when building URLs but "13" is not
part of the map in the site configuration.

A test is added in order to make sure this functionality
will not break (again), see
https://review.typo3.org/c/Packages/TYPO3.CMS/+/62383
for the original fix without tests.
