Revert "api!(jsonrpc): chat_type now contains a variant of a string enum/union. Affected places: FullChat.chat_type, BasicChat.chat_type, ChatListItemFetchResult::ChatListItem.chat_type, Event:: SecurejoinInviterProgress.chat_type and MessageSearchResult.chat_type (#7285)"

This reverts commit a3328ea.
