failure: Some eventsByTag tests fail with Oracle and legacy.ByteArrayReadJournalDao

Started when logical deletion was removed in #569, but that probably didn't work with logicalDelete=false before that either. It showed up with that change because the default for logical delete was changed.

I believe the reason for this issue is because Oracle does not support the boolean data type. Therefore, after PR #569, the functionality stopped working.

It's frustrating because this problem has recurred in PR #731 and has caused me some difficulty.
