Jaeden Amero 2ce22a5079 Stop transactions from being reentrant ...

We want to explicitly disallow creating new transactions when a
transaction is already in progress. However, we were incorrectly
checking for the existence of the injected entropy file before
continuing with creating a transaction. This meant we could have a
transaction already in progress and would be able to still create a new
transaction. It also meant we couldn't start a new transaction if any
entropy had been injected. Check the transaction file instead of the
injected entropy file in order to prevent multiple concurrent
transactions.
