Fix csv snippet error

[PopDaph]

Description

New attempt at fixing this error: Log.

The error occurred because the output of the table query action is:

{
  thinking: "Some thinking",
  query: "The query",
  query_title: "The query title",
  results: [
    {
      'GROUP_CONCAT(DISTINCT "owner")': null,
    },
  ],
}

The fact that the value is null somehow breaks the snippet generation.
I fixed it by keeping the empty line.
Tested locally and now the snippet looks like this:

TOTAL_LINES: 1
"GROUP_CONCAT(DISTINCT ""owner"")"


(end of file)

This means that for an output as is:

{
  thinking: "Some thinking",
  query: "The query",
  query_title: "The query title",
  results: results: [
      {
        DS: "20161",
      },
      {
        DS: "20160",
      },
      {
        DS: "20159",
      },
      {
        DS: null,
      },
      {
        DS: "20157",
      },
    ],
}

Instead of getting:

TOTAL_LINES: 5
DS
20161
20160
20159
20157

(1 lines omitted)

We will get:

TOTAL_LINES: 5
DS
20161
20160
20159

20157

Tests

Locally.

Risk

I'm not sure why we were skipping empty lines and I think it's fine to keep them but I'll confirm with Seb who wrote the code + this is safe to rollback.
