zilencer: Update last_audit_log_update before `sync_license_ledger..`. 

We need to update 'last_audit_log_update' before calling the
'sync_license_ledger_if_needed' method to avoid 'MissingDataError'
due to 'has_stale_audit_log' being True.

Also, we made the code block that creates audit logs,
updates 'last_audit_log_update', and syncs LicenseLedger in
an atomic operation.

This helps to rely on 'last_audit_log_update' to assume
'RemoteRealmAuditLog' and 'LicenseLedger' are up-to-date.
