Watch no longer detects new changes
I couldn't isolate the specific commit or code change, but `skpm-build --watch` breaks on 0.7.1, where I can confirm by downgrading that it still works on 0.7.0.

[Here's a screen grab from 0.7.1](https://drive.google.com/file/d/11a33mTii71RXPVQVBHtu2xrntj-i_vzC/view?usp=sharing). The same actions trigger a rebuild on 0.7.0.

I'm wondering what I might be able to do to help isolate this issue — I'm able to handle technical stuff if need be.
