master (4.7.0 RC)

Describe the bug

After loading the minimal bundle, on render, we should not call renderMarkdown as it is undefined.

This will make sure we render the text as plain text, instead of HTML.

Steps to reproduce

1. Load webchat-minimal.js
2. Type echo **123**

Expected behavior

The bot response should show up as **123** instead of bold 123.
