SFR-2292: Skip clustering records with no title

[kylevillegas93]

Description

• Clustering fails if we try to tokenize a null title
• This change skips trying to cluster records without a title

Testing

python main.py -p ClusterProcess -e local-qa -i single -r 1ad13bf1-e48b-4f8f-8868-457d98b302a8

In this case, one of our NYPL bibs caused us to fail clustering.

A record with no title should not be clustered so that's great to note this.

Great error to catch in the cluster records.
