Bug fix

- Fixed: Bob's fund data not read from blockchain
- Fixed: incorrect senders list passed to readData from blockchain
- Fixed: when data is not saved in DB correctly, do not update LastTx, hence in next refresh, it might get resolved
- Fixed: bugs in Blockchain bonds closing and bob's fund closing
- Merged parse.main and parse.end in Bob's fund module
