UI freeze when watcher cannot find folder

[sudhanv09]

The UI is completely unresponsive due to the added project no longer existing.

Here is the complete log:

Reproduce:

1. Add a project to gitbutler
2. Delete the folder

Thanks @sudhanv09, we'll definitely want to fix.

Even though the behaviour around deleting a project is still to be improved (tracked in #3447 for now), I wasn't able to reproduce the UI freeze described here with the latest version from #3471.

(note that the video also shows delayed popups from the last attempts to reproduce the issue, as well as some error messages)

Thus I think this issue can be considered resolved once #3471 is merged and available in the a non-nightly release.

Closing, as the fix has been released and is available in 0.11.2 or newer.
