No stack trace

I don't know

### How do you reproduce the issue?

- Then print the `slug`
- It is a list of dash characters, not words

### Do you have a unit test that can demonstrate the bug?
No

### Can you identify the location in Bogus' source code where the problem exists?
No

### If the bug is confirmed, would you be willing to submit a PR?

Yes or No? No

Reproduce the issue with `new Faker("fa").Lorem.Slug(7)` and inspect the `Lorem.Slug` entry point together with the Farsi locale data. Done means the call returns random Persian words rather than only dash characters, with a regression test covering the reported behavior.
