Cannot import a deck with modified model

Tried to export a deck, modify template and import back.

My hunch is that it's a 2.1 migration problem:

1. dialog import is not updated
2. the actual dialog was not tested

I'll look into this when I have time, also tagging @friebetill as he did 2.1 support.

There is actually another appearance in node.py
