Fix FindBugs error in DelayedListenerRegistration#getInstance

The ObjectRegistration interface was recently changed to annotate
getInstance with @Nonnull to promise it will not return a null.
However DelayedListenerRegistration could return null if the delegate
is not set yet. In reality, we do not and should not ever call this
method on DelayedListenerRegistration instances so I changed it to
throw UnsupportedOperationException to make it explicit and to avoid
the FindBugs error.
