The local_mode doesn't create node object correctly on chef 12.

[sawanoboly]

at chef 11.16.2, local mode creates node object with node attributes.
but at chef 12.0.0, local mode creates node object without node attributes.
this change (or bug?) breaks https://github.com/higanworks/knife-zero.

Please see the more details chef/chef-zero#99 .

chef-zero stores data to use Chef::ChefFS::FileSystemChefRepositoryFileSystemEntry.write,
but Chef::JSONCompat.from_json at minimize breaks file_contents.
( https://github.com/opscode/chef/blob/12.0.0.rc.0/lib/chef/chef_fs/file_system/chef_repository_file_system_entry.rb#L59-L71 )

#2482 fixes Chef::ChefFS::FileSystemChefRepositoryFileSystemEntry.minimize and data store at local_mode works fine.
