display Cadence log when a transaction fails

Issue To Be Solved

When I add log("my debug statement") in a transaction, the logging is not displayed in the Flow emulator when the transaction fails -- it s only displayed when the transaction passes. This causes some inconvenience for debugging a transaction.

(Optional): Suggest A Solution

Display the Cadence transaction log even if a transaction fails, to make debugging easier
