Fixed a bug where not all threads could be correctly identified while…

… suspending the stress test process.

Fixed a bug where the stress test program wasn't re-started if the first core on the first iteration threw an error and Automatic Curve Optimizer and restart for each core was activated.
(Hopefully) Fixed a bug where for Aida64 the wrong number of worker threads were assumed. It's a fixed lookup table now, so it may still not be correct in all cases.
