Stefan bf29188b2d fix(wallet) add index on transfers(blk_number, loaded)

Improve performance of queries for
- transfer.GetTransfersInRange
- transfer.GetTransfersByAddress
- transfer.GetTransfersByAddressAndBlock
- transfer.GetTransfers
- transfer.GetPreloadedTransactions

For 16952 entries worst case scenario tested with `sqlcipher`:
- Before: Run Time: real 0.897 user 0.728139 sys 0.166714
- After:  Run Time: real 0.001 user 0.000437 sys 0.000189

A single composite index (with the default one) might work better though
