Import Rows are currently identified by the field Fall ID. It should probably be Meldung ID instead.

https://github.com/jshmrtn/hygeia/blob/be2b9ea2d021321031275e8c11aba96ff7afd935/lib/hygeia/import_context/planner/generator/ism_2021_06_11_test.ex#L86

Assumed Bug Reason:

When having two rows in the same import, that reference the same case id, the ON DUPLICATE clause in the insert mutates the same row multiple times. This produces an error.
