cluster-ui: use job lastCompleted time when formatting last refresh time

This fixes a small bug in the TableMetadataJobControl component
where we were reading the last updated time of the job to
determine whether the job completed. This lead to `Invalid Date`
being shown when the job never completed before.

Epic: CRDB-37558

Release note: None
