Network server constructor reads config.Version variable, and testcli.DeployContract writes dummy config.Version which causes race in tests. Avoid this race by moving config.Version initialisation to a separate package and perform it inside test packages init(). Close #3011, close #3017. Signed-off-by: Anna Shaleva <shaleva.ann@nspcc.ru>
