session: deleting an application namespace cleaning up the wrong application

We call application_namespace_cleanup to remove the application which
has a reference to the application namespace when deleting an application
namespace. When we find the matching application namespace, we queue
the ns_index instead of app_index to look for the application.
This may lead to a crash.

Type: fix
