Following up a recent PR that attempted to fix the Filtering of textarea element when using Custom Blacklist, that was always defaulting to disregarding the Custom BL, this PR improves this, because the call the JFilterInput was still forcing to clean up based on the default blacklist.

Following up the recent PR #2199 that attempted to fix the Filtering of Textarea element when using Custom Blacklist for Text Filters, this PR improves on top of that, because the call the JFilterInput call from inside the Worker is still forcing to clean up all tags of the default blacklist, because the param $xssAuto of the JFilterInput::getInstance() method gets the default value (1) which forces cleanup, instead of only cleaning the essentials.
