[wallet] fix zapwallettxes interaction with persistent mempool
zapwallettxes previously did not interact well with persistent mempool. zapwallettxes would cause wallet transactions to be zapped, but they would then be reloaded from the mempool on startup. This commit softsets persistmempool to false if zapwallettxes is enabled so transactions are actually zapped.
