FIX: Optionally linkify URL columns server-side (#330)

Followup da1c99ec2d

We already had the functionality to convert results like
this:

```
|blah_url|
|--------|
|3,https://test.com|
```

To a link clientside, so in the UI it looks like this:

```
<a href="https://test.com">3</a>
```

With the addition of the recurring report to post automation,
and the existing report to PM automation, we also need to be
able to do this server-side, so reports don't come out malformed
if they have these type of count + URL columns.
