Currently, when reaping sessions from memory, if the LogicalSessionCache reaper finds that a logical session hasn't expired, it would skip reaping its transaction sessions from the SessionCatalog entirely including the ones that are expired and not in-use. This could cause the SessionCatalog to end up with a lot of expired sessions if the external client just keeps using the same logical session.

Note that the on-disk states for those expired transactions still get deleted in this step.
