29fed37df3 Fix exception when few pairs with no data do not result in aborting backtest. 
Exception is triggered by backtesting 20210301-20210501 range with BAKE/USDT pair (binance). Pair data starts on 2021-04-30 12:00:00 and after adjusting for startup candles pair dataframe is empty.

Solution: Since there are other pairs with enough data - skip pairs with no data and issue a warning.

Exception:
```
