src: prevent persistent handle resource leaks

Replace v8::Persistent with node::Persistent, a specialization that
resets the persistent handle on destruction.  Prevents accidental
resource leaks when forgetting to call .Reset() manually.

I'm fairly confident this commit fixes a number of resource leaks that
have gone undiagnosed so far.
