------------------
- Fixed a bug in `getPrintableItemsByCategory` (incorrect method call, categories are now in DX).
[aduchene, gbastien]
- Added `testCustomMeeting.test_GetPrintableItemsByCategoryWithBothLateItems`,
moved from `Products.MeetingCharleroi`.
[gbastien]
- Fixed `Migrate_To_4200`, call `addNewSearches` at the end because it needs
`_adaptWFHistoryForItemsAndMeetings` to have been called in the
`_after_reinstall` hook to have correct workflows.
