Unterminated StackProfiler thread in case of failure of benchmark

[Evgeny Mandrikov]

Hi Aleksey,

Seems that there is no notification for profilers in case of failure of
benchmark ( LoopBenchmarkHandler can exit with BenchmarkException before
reaching stopProfilers ) , so that forks won't be terminated if profiler
spawns thread. This is the case for StackProfiler and can be reproduced by
addition of ".addProfiler(StackProfiler.class)" into FailingForkedBenchTest.
