AcocuntReference of import differs from accountreference used in user lifecycle scripts

[rschouten97]

In the import script the accountreference is just a single string of the userid$(importedAccount.Gebruiker), howver the update script uses $actionContext.References.Account.Gebruiker, where the accountreference is an object with the property 'Gebruiker'.
This results in the update updating all users instead of just the single correct one!
