visit_time_ranges() reuses a single "original_duration" variable for two unrelated purposes: the DTSTART->DUE span and the CREATED->COMPLETED span. When a VTODO carries all four properties (a completed task, which most clients write with CREATED and COMPLETED), the second assignment clobbers the first, and the DTSTART/DUE branch of the rfc4791-9.9 table then reconstructs DUE as DTSTART + (COMPLETED - CREATED). The elif chain already implements the RFC table correctly (DTSTART/DUE take precedence over CREATED/COMPLETED), so the CREATED/COMPLETED value is never wanted there. Keep it in its own variable. Effect: such a VTODO is filtered against a bogus interval, both in calendar-query REPORT and in item.find_time_range() (the enclosing range cached for the storage prefilter), so completed tasks go missing from - or wrongly appear in - client results.
