wrong URL for server results in incorrect error message

I submitted a job to a testflinger server using the --server option. This resulted in:

bladernr@galactica:~/development/testflinger$ ./checkflinger -s ob-10 --series bionic --server http://10.193.37.116:8000 test -t usb-only
Initiating testflinger run on ob-10 using server at http://10.193.37.116:8000
ERROR: ld.so: object 'libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (failed to map segment from shared object): ignored.
Job submitted successfully!
job_id: b8c9048a-f81b-463a-bd53-4eab8957a053

I then attempted to poll that job but put in the wrong URL:
bladernr@galactica:~$ testflinger --server http://10.193.37.117:8000 poll b8c9048a-f81b-463a-bd53-4eab8957a053
ERROR: ld.so: object 'libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (failed to map segment from shared object): ignored.
Invalid job id specified. Check the job id to be sure it is correct

Rather than an error indicating that the URL was an invalid server, I got one telling me the jobid is invalid. Whihc is kinda confusing.

Expected:

It should attempt to contact the server at $URL and then tell me "Hey, there's no testflinger server listening at that URL"
