Describe the bug
When a user attempts to upload a file but clicks an upload button that does not correspond to the document field it causes a server error

Janeway version
1.5.0

To Reproduce

1. Go to document management for any article
2. Click "Upload File"
3. Fill in file label
4. Select a document under "New Manuscript File"
5. Click the "Upload" button in the "Figure/Data File" section

Expected behavior
Probably this should cause a form error indicating there is no file to upload but also the interface could be changed so there aren't a bunch of different upload buttons.
