wso2api: businessInformation is taken from OpenAPI document, and can't be overridden

If an OpenAPI document contains contact information, this information is used for the `businessInformation` property of the wso2ApiDefinition. This default, in contrast to the other defaults that come from the OpenAPI document, can't be overridden by setting the `businessInformation` in `Wso2ApiProps.apiDefinition.businessInformation`
