Broken ext and ticket tests

[LourensVeen]

Describe the bug Several of the ext_tests and ticket_tests are currently failing. They've been disabled for now, but should really be fixed:

• [ ] test_jobserver (crashes the entire pytest run)
• [ ] TestLimepy (LimePy itself is broken, see #1102)
• [ ] TestHeatingWind::test_supernova and test_supernova_manuel (different result than expected)
• [ ] TestsForIssue123 (crashes)

Additionally, several warnings are generated when running the ext tests:

To Reproduce With the new setup system, edit ./setup to remove the desired test from BAD_EXT_TESTS, then run ./setup test amuse-ext. The warnings are always printed.

Expected behavior The tests are expected to pass.

Additional context I've disabled these tests for now, so that we can run this in the CI and at least detect when some code change causes other tests to fail. It would be better to get them fixed though.
