Description
A GET request to /v2/repositories/<repo_id>/importers/<importer_id>/schedules/sync/<schedule_id>/ returns a 400 if schedule_id is not a valid bson ObjectId.

Since this information is passed in the url, it should instead be a 404.

To reproduce
The schedule id must not be a bson ObjectId.

$ curl -s -H "Accept: application/json" -H "WebFrameworkSwitch: webpy" -X GET -k -u admin:admin https://localhost/pulp/api/v2/repositories/test/importers/yum_importer/schedules/sync/not_valid_bson_object_id/ | python -mjson.tool

}

Note
This will be fixed in the Django conversion.
