With the root's byte range, diagnostics() reaches get_byte_positions() also
with JSON_DIAGNOSTICS when there is no value, as for a value-initialized
iterator (invalid_iterator.212). get_byte_positions() now returns no range
for a null value, the same change as #6003, so either can be merged first.
In the view, a value that value_path() does not find leaves no tokens, so the
found flag added nothing to the tokens.empty() test.
