Get rid of console.log statements.

Calling JSON.stringify on random objects is potentially dangerous for the
health of the application. In particular, if the object has a string whose
size is many megabytes we might run out of memory before even calling
console.log.

I got rid of the console.log calls entirely because they're not free and they
fill up the console for everybody, even if they're not developing the app.
Getting rid of JSON.stringify(note) was the important change.
Don't roundtrip through JSON to normalize objects.

I had to guess a little bit as to what "normalizeObj" was intended to do but
this seems to work (i.e. I can still sync notes) and it's much, much cheaper.
The object that was causing problems had a string that was many megabytes in
length (28 to be exact) and we were running out of memory deserializing it.

As far as I can tell, the only thing the roundtrip does is strip out undefined
values and functions from the final object, so this accomplishes that by on
serializing the properties that we actually want.
