Fix IsValidJsonNumber() to notice trailing non-alphanumeric garbage.

Commit e09996ff8dee3f70 was one brick shy of a load: it didn't insist
that the detected JSON number be the whole of the supplied string.
This allowed inputs such as "2016-01-01" to be misdetected as valid JSON
numbers.  Per bug #13906 from Dmitry Ryabov.

In passing, be more wary of zero-length input (I'm not sure this can
happen given current callers, but better safe than sorry), and do some
minor cosmetic cleanup.
