vfs: fix reload: failed to add virtual dir entry: file does not exist

This error happened on a restart of the VFS with files to upload into
a new directory on a bucket based backend. Rclone was assuming that
directories created before the restart would still exist, but this is
a bad assumption for bucket based backends which don't really have
directories.

This change creates the pretend directory and thus the directory cache
if the parent directory does not exist when adding a virtual on a
backend which can't have empty directories.
