Suppress logging of deprecated config alternatives

The extension should only recommend usage of non-deprecated config parameters.
There is a small number of deprecated parameters that have their own deprecated
fall-backs. But since they had no default value, the check to print the deprecation
message was positive even when the property was not set explicitly. Adding the
default values removes the deprecation message. This is correct when it is not
explicitly given.
