XWIKI-9336: Quotes are escaped in doc.title livetable column
* The live table JSON should provide raw values. The client side should be responsible for properly encoding the received values based on the context were they are inserted/displayed or based on the 'html' column property. This is a leftover of XWIKI-8594.
