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:
```

f3388ed9aa fix IStrategy: abstract methods still need to pass through return value 
otherwise doing something like:
```py
dataframe = super().populate_indicators(dataframe, ...)
```

won't work, because `dataframe` becomes `None`.

This is needed if one of those methods uses dataframe.copy() instead of
just working on reference. e.g. using `merge_informative` in
`populate_indicator` in a nested class hierarchy
