Some features still need regression tests

[c-prather]

Masterlist of things I've said "that needs a test" about

• Multizone regression test, e.g. match a magnetized Bondi solution after a few iterations
• Restart w/EMHD enabled
• Restart w/Electrons enabled
• Restart w/Face-CT enabled
• Restart w/SMR enabled
• SMR modes convergence
• SMR keeps divB with wacky O-T vortex meshblock breakdown
• SMR keeps divB in small 3D torus problem
• SMR convergence on more tests, e.g. Bondi
• Re-enable all electrons tests not currently run w/CI, with real failure criteria
• Komissarov blast with outflow boundary conditions
• Spherical grid with outflow conditions, outflowing/polar blob
• Mid-MAD test for continued agreement with iharm3d in that mode
• Hubble flow. Implemented but has a bug in the source/boundary
• 2D driven turbulence for e- heating
• "Shadow" test of relative e- entropy in a full 2D SANE model
• Field loop advection in Cartesian
• Field loop advection across pole
• MHD modes across pole
• P->U->P direct inverter tests
• Tests that reductions are calculated correctly by checking history file

@samason4 has recently implemented restart with electrons and I believe he has tested it. He could open a PR to dev.
