The individual requests in the multipartite batch request contain the scheme and host:

/dns/v1/projects/dummyprojectid/managedZones

vs

http://localhost:43754/dns/v1/projects/dummyprojectid/managedZones

Therefore, in LocalDNSHelper in the pickHandler method, we sometime relativize the URI directly and sometimes extract path first. We should investigate if this is the correct way or if we should make the queued batch requests consistent in providing URI without the scheme (by not setting host in the options).
