Address multiple bugs with long tag descriptions

In the previous release a regression was introduced regarding multiline tag descriptions. Part of the description was lost and the indenting wasn't reduced as we did before 5.4. If your application relies on docblock tags and uses the descriptions it is highly recommended to update immediately. And block version 5.4.0 from the allowed versions in your composer.json
