Indeterminate PreparedStatement error hidden when inside a transaction (eclipse-vertx#1558)

See eclipse-vertx#1557

When inside a transaction (autocommit=false), don't try to prepare a statement again, even if the error is due to indeterminate types.

Indeed, the transaction is aborted and new commands are ignored until the transaction is rollbacked.
