Distinguish between origin of empty tables in collation step #38

Currently an error will be raised when the fingerprint table is empty. However this can occur by one of two reasons. The first being that no fingerprints are predicted and the output of CSI is empty. The second being that the output of CSI failed and produced no results. It would be useful to distinguish between these two cases.
