perf scripts python: export-to-postgresql.py: Fix DROP VIEW power_events_view



PostgreSQL can error if power_events_view is not dropped before its
dependent tables e.g.

  Exception: Query failed: ERROR:  cannot drop table mwait because other
  objects depend on it
  DETAIL:  view power_events_view depends on table mwait
