do not use TRUNCATE when refreshing reporter.materialized_simple_record

Previous behavior would break Slony replication after doing a
bib load.  Since a deletion is slower than a truncate, if you're
not using Slony replication, you may prefer to truncate rmsr
prior to calling reporter.enable_materialized_simple_record_trigger.
