12.9 NDU text element migration

[BPMJoannette]

When you migrate a bot using NDU from 12.8 and earlier, text nodes do not get their content migrated.

Visually, the text is not available anymore, but the content element is still tied to the node, and has precedence on the text input in this new UI, so the bot behaves just like it did before, but its content cannot be changed from the UI anymore.

Steps to reproduce the behavior:
Here is a bot to import, skip to step 7:
bot_ndubot_1591029004885.tgz.zip
Alternatively, to create your own:

1. Start Botpress version 12.8
2. From the admin/modules panel, extract and activate NDU
3. Create a bot from the NDU "test bot" template
4. Go to flow design, right click to add a "Send Message" node.
5. Double click it to select or create a text content element.
6. Export the bot
7. Import the bot into 12.9
8. Go to flow design

Say - node-ID is empty

Expected behaviour
Migration of the onEnter content element to the content.formData.text${lang} property, so that text is displayed post-migration and can be edited from the UI, so that the bot uses this edited text.

Environment:

• Version 12.9
