Fix allocations test errors

[MaxenceGollier]

closes #145

See #145 (comment).

I guess that test will fail on lts with this but we should try to make 0 allocations on lts and not the other way around.

💪 QRMumps.jl#136 should fix for Julia 1 now.

Just need to solve on nightly.

[amontoison]

@MaxenceGollier I suggest to use pre (for pre-release) instead of nightly for the unit tests.

[MaxenceGollier]

For your info @amontoison, I was able to solve the issue on Julia pre by updating the wrappedallocs macro, I don't know if you use it in other packages, you might find it useful if you run into similar errors.
I just call the function twice and use the allocated macro on the second call.

I only have the QRMumps.jl related failures now.

Oh, do you do the warm-start this way?
It is neat!
