Port issue-545.sli to py

[otcathatsya]

It looks like the original SLI test may not have covered the intended error case to begin with? The original report specifies that passing integers leads to a crash/exception, though the SLI test seems to use floats only. In either case this is not an issue with python, as even integers are correctly cast.

Edit: it appears that a 2021 commit removed the integer part of the original SLI test since it became obsolete, purpose of the current test is a bit questionable

The key point here was that prior to #704 which fixed #545, NEST would actually crash when SetDefaults() contained unacceptable values. This would happen because we did not catch exceptions inside threads. A proper test for this regression would be to use parameters forcing an exception (e.g., setting a time constant to a negative value) and test for this with pytest.raises(). If NEST then crashed, the test would fail. We don't need to include passing cases here, and we only need to do this for a case with > 1 thread.
