Fix ChangeRebuilderImpl with null account IDs

Browse Source 
The Event comparator had a NPE when used with a null account ID,
which is otherwise supported. This only shows up after comparing a
few more fields, which may be why it hasn't shown up yet. (Or maybe
we didn't have any test cases at all with null IDs.)
