Merge branch 'bugfixes' into 'master'

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.
