Fix for slippage time getting out of sync with algo.
...
Moved grouping by date earlier in the pipeline of generators,
prior to any date-dependent state getting involved. Grouping
pulls from the pipeline until the start of the next group,
which is in the next day. The effect of grouping after
slippage but before handle_data is that slippage and the algo
are out of sync by a transaction.

Adapted test_risk_compare_batch_iterative to work with fixed
