Subject: [PATCH] HTTP code 500 instead of 400 for invalid key during document
 creation

The wrong status code is returned when creating or updating a document
with an invalid key.
Returns:
{u'reason': u'Bad special document member: _invalid_key', u'error':
u'doc_validation'}
HTTPError: 500 Server Error: Internal Server Error
Expected: 400 Bad Request error
