> in 1.0 if a file was both in a jobs cache archives and cache files, and InvalidJobConfException
was thrown.  We should replicate this behavior on mrv2.  We should also extend it so that
if a cache archive or cache file is not going to be downloaded at all because of conflicts
in the names of the symlinks a similar exception is thrown.
