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.
