IDGenerator fails with History Objects

[itsmebasti]

fflib_IDGenerator.generate(CaseHistory.SObjectType) results in :

System.StringException: Invalid id: null000000000001 Class.UP2GO_2T.fflib_IDGenerator.generate: line 41, column 1

Same for Custom__History objects.

Bah.... not really sure what we can do about this tbh, feels like a platform issue. @capeterson any thoughts?

the bigger issue is that xxxHistory objects can't be mocked, even using json.deserialize technique
