[SYCL] Rework of pi tracing test (intel/llvm-test-suite#876)

Reworked check statement, so it does not requires 'const' specifier, as it is not working properly with reworked event and event_impl classes, which are now supporting lazy init with get_native for the exemplars constructed with default constructor.
