several tests failing against local build of master branch

[ctdunc]

Describe the bug
A few of the tests are failing against a local build of master. I am running the latest stable Debian in WSL.

• test_model > test_solve_concurrent segfaults when built against scip compiled with -DAUTOBUILD=on -DTPI=any with soplex. This does not occur on the PyPI version as it is not built with TPI enabled.
• test_model > test_locale fails as pt_PT is an invalid locale.
• test_nonlinear > test_addExprNonLinear fails as y=2.0000163858811364 instead of 2. It may not be respecting the new epsilon?

To Reproduce
pip install .;pytest.
Expected behavior
Tests should pass.

System

• OS: Debian GNU/Linux 12 (bookworm)
• SCIP version: 9
• How did you install pyscipopt? Locally

Hello, @ctdunc, thank you for the issue! Also, thank you for your other awesome issue, sorry for not saying anything. These are just general comments and don't really fix the issues.

• I'm not sure whether I've ever run the parallelism tests since I usually compile SCIP without TPI, but it seems to be causing a bunch of issues (Problems in using concurrent solver, both tny and omp not works #780, among others)
• pt_PT is a valid locale (it's the one I have :) ), but it's not a standard one, I think you need to maybe install it somehow? This may work: sudo apt-get install tzdata locales -y && sudo locale-gen pt_PT && sudo update-locale
• I had already noticed the test_addExprNonLinear one, but I assumed it was a problem with my machine, as it is passing on the pipelines. I have to look into it.

Thank you for clarifying. Mostly wanted to confirm that I was not creating these issues somehow with my local build or missing others in my PR on the other issue

No problem, @ctdunc! But I'll reopen the issue, since this is still something we need to look at :)
