Throw Exception on Invalid Order Filter Query

[mab05k]

When using the Order Filters, the syntax is order[field]=<asc|desc>.

Right now, if a user submits this query with something invalid, like order[field]=true, the filter is not applied and the User has no idea why his response is not ordered as expected.

Can we issue a 400 Response when a value other than asc, desc, or '' are sent in the query?

Probably will be fixed by #1723?

Looks good to me, I'll close this issue. Thanks @teohhanhui !

@teohhanhui I did not look particularly at the order filter descriptions, but #1723 should put the background to order filter validation yes
