Bug fixes

- Fixed: Trade balance not updated correctly
- Fixed: sell-chips were not checked correctly on placing sell orders
- Fixed: sell-chips not added when distributed
- Fixed: sell-chips (FLO) not added when deposited by launch-seller
- Fixed various bugs
- initialPrice will be added to priceHistory table (initially)
