Fix - Finder: Indexer Parsers break search result descriptions #4327

See discussion here: https://github.com/joomla/joomla-cms/issues/4327

*How to test?*

In the comments you can find a link to a page from where you can copy the article text (view source code and copy&paste). For the second issue just copy the example in the description of the linked enty.

Create two articles with the example content. Enter the content in an article and run the indexer of the smart search component. Then go to the frontend and search for the articles. After applying the patch you should not see parts of the HTML code in the first and no spaces in the second article!
