Steps to reproduce

• Create a new Mock (M1469)
• Upload an image to the Mock
• Upload an image to the description field
• Save the Mock

Expected behavior

• The 2 files are attached to the mock so permissions are inherited from the Mock to the files.

Current behavior

• The file uploaded in the mock is attached to the mock and accessible by everyone who has access to the mock (F1812095)
• The file uploaded in the description field has no relation to the Mock and is only visible for the user who uploaded the file. (F1812094)
