Move the "updatedPreference" event listener registration

Browse source 
This patch fixes a situation that'll probably never happen, but nonetheless seems like something that we should address.
Currently the "updatedPreference" listener isn't registered *until after* the preferences have been read and initialized, which leaves a very short window of time where a preference change could theoretically be skipped.
