Unexpected completion

[wycers]

POC：

1. Finish exercises in order while rustlings watch.
2. When the current working exercise is move_semantics2.rs, make a copy of it.
3. The new file move_semantics2 copy.rs is generated, then rustlings outputs ★ All exercises completed! ★ and exits.

I have not verified the file name in the above process is critical or not.
In fact, I am not sure that is an issue ... Maybe I should not do that?

Env:

• rustc 1.44.1 (c7087fe00 2020-06-17)
• cargo 1.44.1 (88ba85757 2020-06-11)
• rustlings 4.0.0

It is a minor bug in the way we watch the exercises folder, it could certainly be improved.

If I may ask, did you stumble upon this by chance? Or did you create that copy deliberately while doing exercises? If so, may I ask why?

I made a copy in order to try some different solutions😂
