Remove compute_stresses_cart precompilation to fix ForwardDiff Dual tag ordering problems

[Technici4n]

Workaround for JuliaDiff/ForwardDiff.jl#714. The precompilation_task.json file is just test/silicon_bands.json without the postscf... I didn't give it more thought for now.

Sounds good, but maybe we should still run this as a test, just to avoid this failing without us noticing in the future ?

[Technici4n]

compute_stresses_cart still runs as a test, it's just that the precompilation now uses a different json file.

[mfherbst]

Oh sorry to be unclear. I thought to run the precompile json file as an extra test to ensure the json itself does not become out of date.

[Technici4n]

It already runs when precompiling AiidaDFTK at the beginning of the tests. Is that sufficient?

[mfherbst]

True, let's hope that works and catches the problems.
