tests: prevent test-hup from hanging forever if the transaction does not start
If the transaction fails to start because of some programing errors, the test
would stay stuck in this while loop forever.
We now added a basic safeguard that abort the loop if nothing happen in 10
seconds. 10 seconds sounds enough to let the server catch up and open a
transaction.
