Robert Nurnberg @ elitebookandJoost VandeVondele c67c1ec603 [bugfix] Guard is_decisive() to avoid assert triggers ...

This PR fixes an oversight in #6818. At least in multithreaded searches the TT scores can be corrupted, and accessing them is racy.

We also increase the number of the threads in our instrumented CI tests to make these assert failures for buggy patches more likely in future.
