Liquidate Returns a List of Order IDs With Any Status

[AlexCatarino]

Expected Behavior

Liquidate method returns a list of order ticket IDs with any status.

Actual Behavior

Only returns IDs of filled orders.

Potential Solution

Remove ticket.Status == OrderStatus.Filled condition.

For consistency with other trading and orders methods, Liquidate should return a list of OrderTicket.

public List<OrderTicket> Liquidate(Symbol symbolToLiquidate = null, string tag = "Liquidated")

Reproducing the Problem

Call Liquidate for daily data. It will create MOO orders, ticket.Status == OrderStatus.Filled is false and the returned list is empty.
