Title: Hotfix for PrefTarget

If a nsIPrefBranch observer emit something other than nsPref:changed then the PrefTarget listener would have improperly emit a prefchange event

I can't think of a way to test this atm, since `nsPref:changed` is the only topic that is emitted atm afaict.

@Mossop maybe you have some idea how to write a test for this?

Is it worth it for now? perhaps I can make a bug about it and punt it for later?
