Fix gtests/ERROR_TEST errors when run in Debug (#15317)

Fixes errors reported by `gtests/ERROR_TEST` when run with a Debug build. Both errors occur due to invalid stream usage.
```
[ RUN      ] DebugAssert.cudf_assert_true
libcudf was not built with stacktrace support.
unknown file: Failure
C++ exception with description "cudf_identify_stream_usage found unexpected stream!" thrown in the test body.

[ RUN      ] DebugAssertDeathTest.cudf_assert_false
libcudf was not built with stacktrace support.
/cudf/cpp/tests/error/error_handling_test.cu:112: Failure
Death test: call_kernel()
    Result: threw an exception.
 Error msg:
[  DEATH   ] 
[  DEATH   ] /cudf/cpp/tests/error/error_handling_test.cu:112:: Caught std::exception-derived exception escaping the death test statement. Exception message: cudf_identify_stream_usage found unexpected stream!

```
Fixes the test logic to use the correct stream. These tests are only built/run with a Debug build.
