Kevin Ansfield 18d7a7b55d Guard against blank strings in json-string fields (#840) ... no issue We've seen an issue where after an import a user record had `tour: ""` which meant they were unable to log in due to JSON parsing of the empty string failing. - add a guard so that an empty string is transformed to `null` before parsing - changed `serialised` to `serialized` to match spelling in all other serializers		2017-08-29 10:03:45 +07:00
