Position_executor - When stopped with keep_position true doesn't show on /executor/positions

[rapcmia]

Describe the bug

When testing #114 using position executor and close it with keep_position=true to recheck if it correctly records position held, observed that it returns empty or zero amounts

The sample response below return the expected responses under grid_executor (sell/short). However, they fail to do so when using position_executor.

  ...trimmed...

• The executor/{executor_id} custom_info return data for held_position_orders (tested two executors)
• These data are not aggregated and correctly displayed on executor/positions/summary returns empty
• For executor/positions/connector/trading_pair, returns flat zero values

Steps to reproduce bug

1. open position_executor and close with keep_position true
2. check executor/positions/summary and ../connector/trading_pair
3. Compare with grid_executor
