Bug 34517: (follow-up) Add test for attribute search field and make cleanup more robust

This patch adds a test to cover the new functionality of searching an attribute not searched by default.

It also moves the addition of objects to the cleanup array right after they are created. Patrons are added to the front of the array to ensure no constraints are violated when deleting. This change ensures that if the tests die before reachign the end, the data generated is still cleaned up.
