workdirs shows error when ~/.sourced does not exist

We have commands that show a nice output when you need to run init before, like this
```
sourced restart
workdir active is not valid: not found
Cannot perform this action, source{d} needs to be initialized first with the 'init' sub command
```

But `workdirs` fails with a message that is not user friendly:
```
sourced workdirs 
lstat /tmp/nope/workdirs: no such file or directory
```
