Subject: [PATCH] Fix/mark previous as read action includes the selected
 chapter (#483)

* Exclude the current chapter in the "mark prev as read" action

* Prevent unnecessary request for first chapter

In case "mark prev as read" gets called for the first chapter, the is no chapter to mark as read, thus, no request has to be sent
