Trust view does not consistently remove deletions

[jw3]

1. Add some trust entries (or start with some)
2. Untrust some of them
3. Deploy
4. Observe that the deleted items are still present
   • this can be random; if they are not left, restart from (1)
5. With deleted leftovers present, add new trust
6. Deploy
7. Observe that the deletions are now gone.
