Omit the traceback for evaluation errors

The traceback of evaluation errors should not be shown during the workflow evaluation (at least using the synchronous evaluation).

For example, the input a = 1 - 1 [m]; print(a) (in file script.vm) yields the following output on the screen with texts script -m workflow -f script.vm -r:

(python-3.10.12) ubuntu@linux4work:~/work/vre-language/examples$ texts script -m workflow -f 12.vm  -r
