Looking at the LocalBundleListener code it checks if the listener is enabled
before going on to check whether the system is shutting down. However the
"isEnabled" check uses the blueprint-injected ConfigurationAdmin service which
is not available during shutdown. Swapping these checks round fixes the issue.
