fix: node_modules watched off relative path (#1328)

* chore: bump chokidar to latest
* test: fix weird output on restart filename
* test: skip old broken test
* fix: node_modules watched off relative path

Fixes #1294
Fixes #1305 (though couldn't confirm - just looks very similar)

I've gone back and forth on this Chokidar option `cwd` and in this fix
I've removed it from the config. I've checked the issues that were
raised that caused me to add the option, and they still appear to pass
in the tests, so I believe it's okay.

However, it _might_ come back in - just a note for Future @remy.
