bugfix: do not check twice the session
bugfix: SubmitOnly feature does not require id_rsa

This feature required that the private ssh key of the vmchecker is
usable by www-data. The fix uses the assumption that the storer and the
vmchecker are on the same machine. This assumption is made in several
places throughout this project.
