Issue MDL-46598: Robust handling of bad grade import data
If data in a column being imported has a bad value, like a letter “A�?, the import can fail in two different ways. If the instructor maps the column in the data to an existing grade item, we just need better diagnostic message. IF the instructor maps the column to a “NEW GRADE ITEM�?, the import fails with a database error.
