Revert "save trace of the found bug (#533)"

[Raz0r]

Hello, this reverts commit 6b1c2d8.

I misunderstood get_current_input_idx(), the correct identifier is corpus_idx. However, it appears that the trace file for the corresponding corpus_idx is not yet written when ityfuzz reports a vulnerability, it just exits and the final coverage is not collected. This is because CoverageStage is executed after ConcolicStage which immediately exits when a bug is found.

The only workaround is to use --run-forever, in this case the trace file with the solution does appear, but it requires to manually stop ityfuzz.
