Fixed issue #3940: PHP error when running a a survey with conditions …

…based on Tokens but no token table exists.

Fixed unreported issue: issue when a survey doesn't display any question due to conditions (based on tokens).
Dev: the last issue may not be completely fixed cause there is no end-page after the auto-submit, but at least there is no php error anymore
