Koreader: Statistics / All Books shows only currently opened book.

• KOReader version: v2015.11-485-gbfa4bcd and LATEST nighty
• Device: Kobo Aura H2O, Kobo Aura 6''
  

  Issue

Is something wrong with the statistics plugin of the latest nighty builds?
I read and complete some books, but the Statistics / All Books always shows the stats of the currently opened book.
After some days of searching I came up with this: On latest nighties the selected option and stats of every book is stored in the current book folder as: xxxxxxx.epub.lua and thats all... If I want to check the stats on a specific book it must to be opened and then select Statistics / All Books.
On the stable Koreader version the stats info stored in the statistics folder as: xxxxxxx.stat file and always shows the stats info of all books at statistics / Total.
My first thought is to use the statistics plugin of the stable version to the latest nighty. But, in that case I loose all my tracks and stats of my reading books. Except if I'll be able to convert the epub.lua file to .stat. (I don't know how to do that, of course...)
There's anybody have a solution for that matter?

Confirm that it is broken by a recent refactoring. We will fix it.
