Problematic behavior

1. In the document app, click [+ New] > Uploaded file
2. Manually enter its title (e.g My file)
3. Select a file to upload

--> The title of the document is not "My file" anymore, it matches the selected file's name.

Proposition

When a file title has been manually set, we should not override it.

It should be overridden only when:

1. The title was empty -> will match selected file's name
2. The title matches the selected file's name and another file is selected -> will match newly selected file's name
