Summary: Combine multiple db updates in
C4::ImportBatch::BatchCommitRecords for
efficiency/avoiding possible deadlocks

When replacing existing records BatchCommitRecords will the table
import_records will be updated three times for three different fields by three
different queries. Not only is this inefficient ( especially for large batches
), it seems that this is causing the dreaded "Lock wait timeout exceeded; try
restarting transaction" error on some mysql/mariadb configurations.
