Previously, the shutdown hook was only registered once refresh has
completed. If the JVM was shut down during refresh (or after refresh
and before the hook was registered) the hook wouldn't run and the
partially refreshed context would not be cleaned up.

This commit moves the registration of the shutdown hook to before
refresh processing begins. This ensures that the hook is available
to clean up the context if the JVM is shutdown while refresh is in
progress.
