[FIX] Trade filter on history page

Trade filter shows only partially/fully funded trades. I would call this a feature, but it's classified as a bug in Jira, hence the [FIX] label.

[Jira RT-1835](https://ripplelabs.atlassian.net/browse/RT-1835)
[Bountysource](https://www.bountysource.com/issues/2842682-create-trade-filter-in-history-tab)

Modified since last pull request. "orders" filter is now identical to earlier "offers" filter.
@Madsn my mistake..
