In txn_clone.py, non-essential test transaction tx2 was asserted
to be unconfirmed, but would occasionally confirm depending on
network behavior. Fix by explicitly sharing with miner and
checking for 1 confirmation.
Reduce required conflict tests from 4 to 2, by moving one invocation
each of txn_clone.py and txn_doublespend.py to the extented test
section. This saves about 15 seconds per test run for me.
Does what the old txnmall.sh test did.
Creates an equivalent malleated clone and tests that SyncMetaData
syncs the accounting effects from the original transaction to the
confirmed clone.
