Weird C++ test failure in AsyncCallback

[cmnrd]

In this test run a weird error occurred. The AsyncCallback test prints a negative elapsed logical time:

Execution output:
    [INFO]  Starting the execution
    Asynchronous callback 0: Assigned logical time greater than start time by 178363000 nsecs
    Asynchronous callback 1: Assigned logical time greater than start time by 178376000 nsecs

    Asynchronous callback 14: Assigned logical time greater than start time by -2621918000 nsecs
    ERROR: Expected logical time to be larger than 1500000000 nsecs

I am a bit clueless as to what might be causing this... and this requires further investigation.

I think this is fixed by lf-lang/reactor-cpp#31. However, there is still another problem occurring for AsyncCallback on Windows: #1502
