This is creating and linking a Placeholder logbookentry dated 1st Jan. in the relevant
year. This is pointless but it is needed because found_by is a ForeignKey in the db
and we can't be arsed to fudge this properly with a null.(July 2020)
Linking to a passage in a SVX file might be more interesting as the QM does sometimes
have the passage name, e.g. in 204/qm.csv

The CSV file does not have the exact date for the QM, only the year, so links to
survex files might be ambiguous. But potentially useful?"""
