Bug 32255: Resolve "Cannot use file upload in batch record modification"

When using the batch record modification tool with a file of biblionumbers, nothing happens. When we click 'Continue' the file is somehow removed before continuing.

To test:
1. Get a file of biblionumbers (if you already have a file, proceed to step 2)
   1.1. Go to Reports
   1.2. Click on 'Create from SQL'
   1.3. Enter a report name (e.g. biblionumbers)
   1.4. Enter the following SQL query

SELECT biblionumber FROM biblio LIMIT 100

   1.5. Click 'Save report'
   1.6. Click 'Run report'
   1.7. Click 'Download' > 'Tab separated text'

2. Create a MARC modification template (if you already have a MARC modification template, proceed to step 3)
   2.1. Go to Cataloging > MARC modification template
   2.2. Click 'New template'
   2.3. Enter a template name (e.g. Add note)
   2.4. Click 'Submit'
   2.5. Click 'New action'
   2.6. Choose
        - Add new
        - Field 500 a
        - with value Note
   2.7. Click 'Add action'

3. Batch modify records
   3.1. Go to Cataloging > Batch record modification
   3.2. In the 'Upload a file tab', choose the biblionumber file
   --> Note that the name of the file appears next to the Choose button
   3.3. In 'Template', select the MARC modification template
   3.4. Click 'Continue'
   --> The name of the file disappears next to the Choose button and goes back to 'No file chosen'
   --> Message 'No records were modified

4. Apply path
   4.1. Procede step 3.
   4.2. See that we can see the list now
