Subject: [PATCH] Ignore reader when going back in app history

Navigation back through the apps back button should not open the reader again.
This is mostly a preparation for being able to open the manga page from the reader, regardless of if it was the previous page or not, in the future, in that case, the reader will be in the history stack and would be incorrectly opened through the back button
