Issue with default_content_deploy

The default_content_deploy module works by exporting content (node/term/etc) data into JSON files. When better_normalizers is disabled, running a Default Content Deploy import can yield the following error:

In ContentEntityBase.php line 616:
Field data is unknown.

This is because the JSON data contains a "data" key added by better_normalizers, and when the module is disabled DCD no longer knows what to do with this key. I fixed this by manually removing the "data" key from the JSON.

I believe both modules are probably working correctly here but this behavior confused me for a bit so I thought I'd document it in case it bites anyone else.
