handle execve() errors gracefully

duylethanh commented 3 years ago

This PR contains the following:

fix #102 (the .status file will be created even if simexpal can not find the executable), this also fixed a bug where experiments were shown as started when the executable was not found
added unit test for experiments with missing programs

In the launch/common.py I mainly wrapped


child = subprocess.Popen(cmd, cwd=cwd, env=environ,
                stdout=stdout, stderr=stderr)

in a try/except block and put the code below it in the else case.
