Tests fail (with Data::Walk 2.00)

[eserte]

A number of tests started to fail on my smoker machines. Statistical analysis suggests that the problem is caused by recent Data::Walk versions:

R^2= 1.000, N= 61, K= 2

@eserte Thanks for reporting it. It's due to $Data::Walk::type is "HASH" but $Data::Walk::container is not hash data. https://github.com/zigorou/perl-JSV/blob/master/lib/JSV/Reference.pm#L95-L101

I'll investigate it deeply.
