JSON with u prefix

[pvanderlinden]

If you download a table with json data (postgresql), the CSV contains illegal json, all strings are prefixed with a u.

Example:

Content in database:
{'test': 'json'}
CSV export:
{u'test': u'json'}

Technical details:

• Redash Version: 8.0.0.b32245
• Browser/OS: Not relevant
• How did you install Redash: docker (kubernetes)

This is fixed in V9.

I duplicated it on our demo instance (V7) but could not recreate in the preview instance.
