Changing the attachment of a file is not completely taken into account by Drive

Steps to reproduce:

1. Create a file Architecture.pdf.
2. Edit it with Drive.
   -> File is now in the Locally Edited collection.
3. Edit the file in the Platform and change file for a .jpg file.
   -> In the Locally Edited folder, file is still called Architecture, but trying to open it with Acrobat Reader fails. Opening it with a Picture app works fine.
