Subject: [PATCH] Bug 24294: Add default value support for control fields in
 ACQ framework

When trying to add an order using the ACQ framework with a 008@ tag,
Koha explodes:

Control fields (generally, just tags below 010) do not have subfields,
use data() at /home/vagrant/kohaclone/C4/Acquisition.pm line 3272.

Test plan:
Set a default value for a control field in the ACQ framework
Turn on UseACQFrameworkForBiblioRecords
Create a new order from a new record
The default value should be displayed
Save
=> No crash
