Bug 25006: Make Koha::Item->as_marc_field skip undefined subfields 

This patch makes as_marc_field skip subfields that don't have a value or
contains an empty string (replicating C4::Items:1021 logic).

To test:
1. Apply the regression tests patch
2. Run:
   $ kshell
  k$ prove t/db_dependent/Koha/Item.t
=> FAIL: Tests fail because the generated MARC::Field contains undef
subfields.
3. Apply this patch
4. Repeat 2.
=> SUCCESS: Tests pass! Undefined and empty subfields are skipped!
5. Sign off :-D
