insane: Ensure that `src-uri-bad` fails correctly

`src-uri-bad` is missing the required call to `oe.qa.exit_if_errors` so
the corresponding task is not marked as failed when the QA check is
classified as an error.

This issue was fixed by the introduction of the do_recipe_qa task in
OE-core (e0c71367ab59021fc430ef215bbfc3b525036ba4) which is not part
of kirkstone yet.
