Unable to upload multiple files with the same name

[jaw12346]

Describe the bug
When attempting to upload a file named "filename.pdf" to school "a" and course "b", the file successfully uploads, but when another file named "filename.pdf" is uploaded to school "c" and course "d" the database does not update.

Expected behavior
Files with the same name should be allowed to be uploaded both to the same school/course and to the database as a whole.
