fix: a problem with MarketDataCache, when there is a last not completed candle

[acheshkov]

If the last candle is not completed it is not get into the cache. The next time, retrieving candles, if the last candle have not yet completed, the following code

def _with_saving_into_cache(
        self,
        storage: InstrumentMarketDataStorage,
        from_net: Iterable[HistoricCandle],
    ) -> Iterable[HistoricCandle]:
        candles = list(from_net)
        if candles:
            complete_candles = list(self._filter_complete_candles(candles))
            complete_candle_times = [candle.time for candle in complete_candles]
            complete_net_range = (
                min(complete_candle_times),
                max(complete_candle_times),
            )

will throw an exception because complete_candle_times is empty and min of empty list is not defined. The fix is instead of checking size of candles list we need to check size of complete_candles.

The exception traceback example:
