Update test_run_detail fixture after altering Bundle model.
Update test_run_detail fixture after altering Bundle model.

It seems that the serialized fixtures use model field names, not database
column names. After we added _gz_content and renamed the old content to
_raw_content loading this fixture failed which lead to a few failing tests.

This simple patch corrects this issue by updating the fixture to use the new
field name.
