Fix filenames for files exported with CLI (#2932)

Filenames were created with the username of the current user. However,
when we export the files with the CLI, the current user is "_".

This commit makes the username always required in the `exportFile`
method so we make sure to always manipulate a real value. Consequently,
the filenames can be formatted correctly.

Obviously, this has absolutely no impacts since the CLI doesn't consider
the HTTP headers. It just makes things a bit more clear. It's a first
step to remove the concept of "default user".
