We have a saved version 10 db that has 1 of each type of leafentry, and 1 of each (interesting) type of message
We have an LE_COMMITTED,
and XID=0 and XID!=0 versions of:  LE_PROVPAIR, LE_PROVDEL, LE_BOTH

For messages, the loading logic doesn't care about the type at all.
The upgrade logic cares only whether XID is 0, so we have one with 0, one with non 0.
