When dealing with inline @see or @link tags and having a relative method or property type
like LinkDescriptor::setLink() and a namespace alias like phpDocumentor\Descriptor\Tag\LinkDescriptor
Collection::expand() was checking if LinkDescriptor::setLink() could be found in the namespace aliases.
This would never be true.
In this fix, the method or type (for instance ::setLink()) part is removed for comparison
and later re-added when generating the full name
