Client errors are quite often wrapped in context. When checking a specific error, it is required not to lose the ability to determine it, regardless of the attached context. In previous implementation `IsErr*` functions didn't support wrapped errors. Make `IsErr*` functions to preliminarily unwrap `error` argument before type assertion. Use `errors.Unwrap` for this instead of `errors.As` since the latter has the overhead of filling in an error. Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
