jitterbit/get-changed-files@v1 should continue-on-error

as of jitterbit/get-changed-files#7 and others this is considered a bug by 'get-changed-files' author. On error there are still the correct list of files. In worst case we won't get any files and it isn't 'the end of the world' for us clearly.
