Currently replies to messages are handled in status-react.
This causes some issues with the fact that sometimes replies might come
out of order, they might be offloaded to the database etc.
This commit changes the behavior so that status-go always returns the
replies, and in case a reply comes out of order (first the reply, later
the message being replied to), it will include in the messages the
updated message.
It also adds some fields (RTL,Replace,LineCount) to the database which
were not previously saved, resulting in some potential bugs.
The method that we use to pull replies is currently a bit naive, we just
pull all the message again from the database, but has the advantage of
being simple. It will go through performance testing to make sure
performnace are acceptable, if so I think it's reasonable to avoid some
complexity.
