[Access] Log script exec mismatches as error

[peterargue]

Update the Access node's script execution comparer to log result and error mismatches using error level. This makes debugging issues easier on production nodes with a lot of traffic.

mismatches are very rare, so this should only generate a handful of new logs per hour.
