Bug 25751: Add ORDERED in dropdown list of suggestion's statuses

The status "ORDERED" is missing from the pull down list of
status values when editing a suggestion, so the first
option is selected "No status".

This leads to data loss when editing a suggestion in the
status "ORDERED". Worse: the status can't be reset to
"ORDERED" and so no AVAILABLE notice can be sent to the patron.

Test plan:
- Create a suggestion, accept it, create a new order from this suggestion.
- Verify status is "ORDERED"
- Edit the suggestion
=> Without this patch the dropdown list does not have
   "Ordered", and if you save you lost the status
=> With this patch applied the dropdown list has "Ordered"
   preselected. You can save and preserve the status.
