v1.5.1

Fix issues related to the tx_filter.
To recap:

/api/chain/tx_by_filter?arg0=<b58(sol)>
now naturally checks if the sol is included in the chain

Queries on accounts with tons of transactions will work now

to rebuild ALL CHAIN filters you can use

DB.Entry.Hashbuilder.clear_all()
DB.Entry.Hashbuilder.start()

otherwise itl start building new filters from when you launch.

you should still delete all the old filters via

RocksDB.get_cf_size(:tx_filter)
DB.Entry.Hashbuilder.clear_all()

size of optimized filters should be approx 22G for full chain. If your size is over 30G delete the old filters.
