LP1999401: Don't apply magic statuses from holdings editor templates

1. Create a new template in the holdings template editor with a few
different values in various fields.
2. Include a "magic" status in your template (like Lost or In
Transit).  To select it, you can type the first few characters
then press <Tab>.
3. Save your template.
4. Apply your template to an item.
5. Note that the copy status has changed to a magic status.
6. Apply this patch.
7. Try applying your template to another item.
8. Note that the copy status field doesn't change this time,
but other fields from your template should still apply.
