Buy / Sell should not be stored per order type in local storage

[JonRay15]

The Chore

Currently Buy / Sell is being stored specific to the order type.

So the following bad scenario occurs:

1. I happen to have selected limit order at first
2. I decide I want to sell and set that
3. I decide actually I need a market order and select it
4. Suddently I am back on buy, because the last time I was on market order on this market I was on buy
5. Without noticing it I end up buying instead and am BIG SAD

Acceptance criteria

• BUY / SELL should be independent of the order type
• Only key the stored deal ticket state based on the market ID alone
• BUY / SELL should persist and never change based on other inputs ... only by you actually setting it
