MD-1661: Trigger course_module_updated event on date save (PR moodleou#50)

Add final save_new_dates() wrapper method to both base extractor classes:
- report_editdates_mod_date_extractor: calls save_dates() then triggers
  \core\event\course_module_updated so calendar and other observers react
- report_editdates_block_date_extractor: calls save_dates() for consistent API

Update index.php to call save_new_dates() instead of save_dates() for
both module and block date updates.
