#19299: Foreign keys using to_field and having legitimate empty string values
fail
with NULL errors

----------------------------------------------+--------------------
If one table references another table with a foreign
key using a to_field that's a string, and the target column has an empty
string as a possible value, the ORM would remap it to None, and thus
NULL, which is not the same, and which breaks the relation.
