Bug 10887: Batch item deletion -- doesn't need Use default values section

To test:
1. Go to Home > Tools > Batch item deletion
2. Notice that there is an unnecessary option for "use default values
section" to "Populate fields with default values from default work"
3. Apply the patch.
4. Check that this section has disappeared.
