Avoid re-loading completion from the history file after each query

Browse Source 
By default replxx reload history from the file in
replxx::Replxx::history_save(), and this will overlaps current session
history with the history from other sessions, and this does not looks a
great idea (bash and other interpreters don't do this).

So to avoid this, use separate replxx::Replxx instance.
