In some places we panic, in some we return error, in some (audit) just return a client. However in all of the places static client is created immediately before the sugared-client creation. This commit makes all constructors to just return a client for the sake of code simplification and unification. Signed-off-by: Evgenii Stratonikov <evgeniy@nspcc.ru>
