drive-by fix: this was not logging the number before.

I don't think exnref values can flow out to JS, so I don't think it makes sense to try to log them.

Right, thanks, I always forget that tricky part of the spec... Done.

These functions receive a reference value. We cannot log their
internals, but we can try to do some operations on them, and
this gets more such values moving across the JS/wasm
boundary. Future fuzzing of configureAll will build on this.
To achieve this, the
logValuemethod had to be moved up inthe fuzzer, so we can use it from another place. The only
change there is to make it stop printing newlines all the time
(and let the caller do it, if needed).
