ComicK source grouped chapters overwrite each other

[Mqisty]

A while ago grouping chapters was added to the ComicK source which groups same chapters from different sources so there aren't duplicates for the same chapters. This has been great but one issue I've experienced is when, for example, ThunderScans uploads a chapter and then AsuraScans uploads the same chapter some time after. If you have already read the chapter when ThunderScans uploads it it will get marked as unread when AsuraScans uploads the same chapter. This does not always happen and when it does it usually happens with Asura so it might be an alphabetical order thing I'm not sure.
