Log Message:
-----------
[SLP] Fix crash caused by reorderBottomToTop().
The crash is caused by incorrect order set by reorderBottomToTop(), which
happens when it is reordering a TreeEntry which has a user that has already been
reordered earlier. Please see the detailed description in the lit test.
