Invalidate grains table for failed clustering

Previously, if the user re-ran the clustering, and no grains were found, the grains table would not be invalidated, and some results would appear. Invalidate the grains table so that this does not happen. Fixes: #1715 Signed-off-by: Patrick Avery <[email protected]>
