Cannot Sell with a Negative Balance

If you have a negative balance, you should be able to sell shares if that will cause your balance to increase. Currently this is not allowed in the Beta UI.

I also cannot sell shares with a positive balance. I now have a positive balance of 100 DAI. I want to sell nTrump at 0.90. However the beta UI only lets me sell 1000 shares as it believes that selling my shares costs me 0.10/share, when in fact I'm making 0.90/share (minus the 0.01% fee).
