Fix bugs in CBS service responses

SoapOrderHeaderService and SoapOrderLineService had 'typos' in the constructors of the service response. The comparison for the return value of strcasecmp was inside the function call, not after it, so PHP got all confused and was returning the length of the strings rather than a boolean value.

composer.json has already been incremented a patch version for a new release.
