Bug 35885: Sort vendors by name by default

Signed-off-by: Magnus Enger <magnus@libriotech.no>
To reproduce:
- Set ERMModule = Enable
- In the Acquisitions module I added 4 vendors, with names
  X, A, C, Y, in that order
- Went to E-resource management > Agreements > New agreement
- In the "Vendor" dropdown, the vendors are listed in the
  order they were entered: X, A, C, Y

To test:
- Applied the patch + restart_all + run "yarn js:build" in the
  cloned Koha repo inside KTD
- Shift-reload the "New agreement" page
- Vendors are in alphabetical order
