The template replacer feature throws a nullref exception if the template contains unknown content properties in a parameter expression.
This is a problem in case of webhooks, because when we save a webhook subscription with a custom payload, we have to check if the json is formatted correctly. And we can only do that if we replace the parameters with dummy values first.
Solution: the template replaces should not throw an exception in case of unknown properties - simply insert an empty value.
