Tree rank cannot be deleted in some cases after changing a rank's rankId

Describe the bug

From @combs-a

Did find a strange behavior with removing in that if you change the rank of a TreeDefItem, then you can no longer remove it from the tree, but not sure how to recreate it--I tested the same steps on the Taxon tree and tried to recreate it on the Tectonic Unit tree, but it worked as expected both times (still was able to delete the rank).

It says that it cannot be deleted because it's referenced by another tree rank, but it doesn't actually redirect to the tree rank when I click on it--it goes to the tree definition form.

Link to the tree with the undeleteable rank: https://chadrontest2migration5345-issue-5333.test.specifysystems.org/specify/tree/tectonicunit/?conformation=%7E-

Steps to reproduce

1. Change rankId of a tree rank smaller than its parent's rankId
2. The page will refresh
3. Try to delete the rank you just modified
4. Delete blocker says rank is referenced by another tree and cannot be deleted

Expected behavior
Rank should get deleted
