Fix CLI crash when null is thrown

Browse source 
Before:

```
$ ./bin/coffee -e 'throw null'
/src/coffee-script/lib/coffee-script/command.js:251
      message = err.stack || ("" + err);
                   ^

TypeError: Cannot read property 'stack' of null
  at compileScript ...
```

After:

```
$ ./bin/coffee -e 'throw null'
null
```

Supersedes and closes #4135.
