Fix chrome 69 + some theme data related to chats

• Cleaned up Chats theme data in pleromafe.js (slots definitions), had quite a lot of problems by itself
• Added workaround to sort() to make it stable on older browsers (i.e. Array.sort(_ => 0) not returning array with same ordering as before)

patch is live on sgsgb

changed the description

thank you, I'll test it real quick on my instance too with different themes

older chrome seems to work just fine now, great! older samsung internet on my phone still doesn't work but it doesn't work on some older pleroma instances either so it's something different anyway (and it doesn't give me any logs so lets not waste time with that)
