Fix docblock tag descriptions

Browse Source 
Newlines and whitespaces were not handled as before. This caused
issues for some users because our indent-recuction was broken.
The cause seems to be an upstream issue in phpstan parser which
is not resolved yet. But this work around post processing the tokens
helps us to make it work as before.
