HHH-18513: Session Metrics for pre-partial-flushes are wrong

StatisticalLoggingSessionEventListener was incorrectly calculating the pre-partial-flush duration (probably due to a variable typo that passed review in commit e4e26ee).

It seems that there was an error in the database setup for the oracle test. The tests fail with a "cannot connect to database" error (which also seems unrelated to the proposed change):

SessionFactoryTesting > initializationError FAILED
    org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment] due to: Error calling Driver.connect() [ORA-12514: Cannot connect to database. Service freepdb1 is not registered with the listener at host localhost port 1521.

There was also an error during the "Start database" task:

SQL> ALTER DATABASE OPEN

Is this a temporary/flaky error in the oracle database setup? If so, could you please retry the build job? Apparently, I don't have the rights to do so.
