Hi,
I tried to install Mailman & HyperKitty according to the installation instructions and do `mailman-web migrate`, but failed.
```log

Ok, I installed mistune 2.0.4 and retried `mailman-web migrate` but failied yet.

```
And then, I modified hyperkitty/lib/renderer.py as below:

Then retried, I migrated databases successfully. Is this a bug?
