Configure cloudstorage to work with ontario_theme

[KatiRG]

Cloudstorage installed out of the box works with vanilla ckan but not ontario_theme.

Some issues:

• SSL error with xloader, both with certificates generated with openssl and with mkcert:

  ckanext.xloader.job_exceptions.HTTPError: b"HTTPSConnectionPool(host='localhost', port=443): Max retries exceeded with url: ... (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate (_ssl.c:1131)'))) 

• internal server error after uploading a test file with the UI (various errors in uwsgi.ERR)

Adjustments to do:

Replacing ResourceUpload library with ResourceCloudStorage in plugin.py throws a few things off:

• add a check in get_translated() in helpers.py because sometimes the dictionary element is contained in a string for some fields:

  def get_translated(data_dict, field):
  language = i18n.get_lang()
  try:
      return eval(data_dict[field + u'_translated'])[language] if isinstance(data_dict[field + u'_translated'], str) else data_dict[field + u'_translated'][language]
  except KeyError:
      val = data_dict.get(field, '')
      return _(val) if val and isinstance(val, string_types) else val

• get_date_range() in plugin.py() no longer properly handles null dates, so checks need to be added
