Bug 29255: Built-in offline circulation broken with SQL error

This patch makes a minor correction to one of the queries used when
synchronizing transactions in the built-in offline circulation system.
This fixes the error:

DBD::mysql::st execute failed: Column 'branchcode' in field list is
ambiguous at /kohadevbox/koha/offline_circ/download.pl line 84

To test you must be using a browser which still supports
applicationCache (Firefox before version 81, Chrome before version 94).

- Apply the patch and restart services.
- Enable the AllowOfflineCirculation system preference.
- Go to Circulation -> Built-in offline circulation interface.
- Click "Synchronize."
- Click the "Download records" button.
- After the page refreshes you should see updated dates where it lists
  "last synced" information.
