Description
Extracting data for the related object from a queryset with a self referential one to one field gets the wrong data (incorrect columns) from the query when using a select_related with the reverse field.
The incorrect columns are introduced by the sqlcompiler mistaking the reverse select_related path as a part of a multiple concrete model inheritance structure.
The proposed fix tests for self-referential relationships and avoids the multiple concrete model inheritance path in those instances.
Test added and all other tests are passing.
