A crash leaving chat is fixed.
The issue was very hidden cause everything looks ok, at first glance, but not, the thing is that
"messages" exposed to qml were deleted from ChatsView and signals beginRemoveRows and
endRemoveRows were emitted for CatsView abstract list model instead for MessageView abstract list
model. That results in an app crash in some moments (not always reproducible, but often).
Fixes: #3005
Feature added. Firstly we check if the searched message is already displayed and if yes simply jump
to it, if not then we are loading new 20 messages in the past using cursor and check if the
searched message's id is among those received messages. We do that in a loop till we find the
message we are searching for.

Changes made here were necessary in order to have good base to requested develop feature.
- duplicated methods are removed
- loading messages either on start (initial loading) or loading more messages requested by
scrolling in the chat view is now done in separate thread (asynchronous) instead as it was earlier,
done in the main thread
- new file is added for storing async tasks for chat part only
- ChatModel (from status/chat.nim) is QObject instance now, so it may handle async job in a slot
- a job requested from the view is done in separate thread and view is notified about the changes
using signal/slot mechanism
This is not refactoring, but minimal update to have clear situation for further changes
Fixes: #3005
Searching messages by some term for a specific channel is added on the side of status-go and an
appropriate part on the side of nim is developed accordingly.
Fixes: #2912
Current code adapted to handle future changes on message search (like searching message in multiple
channels).
Memory leak which was happening in qml assigning (copying) MessageItem to qml variable messageItem
(where that qml variable messageItem was never deleted) is fixed.
