Fix for generation of invalid json

[dgsuarez]

Seems like the fix introduced in f54a97c has a couple of issues:

• It doesn't insert the newline for arrays
• It inserts newlines when it finds {} or [] inside a string in the json document, which makes it an invalid document.

We've ran into the second issue, it's preventing us from upgrading since some of our pipelines fail.

The solution is hacky, it relies on the json being pretty formatted. In that case each line should have a single value, and the {} or [], with an extra , should be the last content in the line.

{
  "empty_array": [],
  "other": {
    "more": "fields"
  },
  "empty_hash": {}
}
