Passing an active URI to the Flux handle object fails. #2456
Description
So when testing to see if I could remove the step of having to flux proxy in Maestro, I encountered the following in the test of passing the URI to the Flux handle object. To my understanding, this should have succeeded so there's something that seems to be happening here.
The test was simply just loading our version of Flux from spack and then scheduling it. I then opened up a new terminal, spack loaded Flux, and used ipython to try and access the running instance through the handle object.
