9d65ad365c539557e969a35d22723d92e0b422fe Clear vTxHashes when mapTx is cleared (Peter Bushnell)

Pull request description:

  vTxHashes is a vector of all entries in mapTx, if you clear one you should clear the other, lest someone try to use the txiter in vTxHashes which would result in a segfault.
