Description

Reason:
A user may want to add multiple chats in an existing or new folder, which was impossible YET.
I tested it thoroughly, previously I was having some FOREIGN KEY CONFLICT exception which crashed the app everytime when I try to "select all" chats and add it to an existing folder. This is not reproducing it for me. Let me know if anyone is able to reproduce it.

Next plans:
Remove from Folder for multi-select. Let me know if this sounds good.

I have also observed many initialization improvements in the code that we can improve to make the app opening time faster. Like Lazily adding the callbacks and more. Let me know if those PRs are welcomed.

The issue was caused by allowing to add an archived chat to a folder. If an archived chat was added to any folder and then we tried to "select all" chats and then add them to any folder, the app crashed with android.database.sqlite.SQLiteConstraintException: FullCode: 787 | ErrorCode: 19 | ExtendedErrorCode: 3 | Message: FOREIGN KEY constraint failed | ExtraMessage: null.
Fixed this by not allowing "add to folder" from archived chats screen.
