fix comments markdown

Browse Source 
in v4, the switch to QtWebEngine introduced a bug where, in "HTML comments", paragraphs with a single <br> produced an visual extra gap in the render, problem will have been solved by using non-breaking space <p>&nbsp;</p>
(topic https://www.mobileread.com/forums/showthread.php?t=325991)

However, the "calibre.library.comments > markdown" still produces HTML with <p><br></p> causing the rendering of "Markdown comments" in Book Details (and Book Info) to still have this extra gap.
This commit is to fix this and do a more consistent rendering between "HTML comments" and "Markdown comments"
