Test test_is_nonzero make expected exception inline (#37128)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/37128
In certain build modes (in fbcode, building a .par) the mechanism to get test output "expect" files doesn't work.
All other tests in test_torch.py already had assertExpectedInline instead of assertExpected, with the expected result inline in the file.
There was no equivalent for assertExpectedRaises, so I added one, and changed the tests for test_is_nonzero (the only test using this)
Test Plan: CI, specifically the test test_is_nonzero should pass
