Activate trimming for bid_order and ask_order tables

[frankTheTank72]

The tables bid_order and ask_order have the same concept as all derived tables with the latest column, but those tables are not trimmed if the DB.trimDerivedTables = on is set in the config for the node.

The concept is simple - active orders have latest = 1 on the newest entry and cancelled orders or filled orders stay with all records on latest = 0 in the table.

We can remove those entries. Currently we have 32MB of data in those tables which could be freed.
