Code disappears after formatting an already formatted file

[lukaszcz]

The entire file text disappears.

This is due to the anoma/juvix#2173 missing from the release.
@paulcadman is currently reapplying it in this PR in Juvix: anoma/juvix#2205

There's a good point from @lukaszcz in anoma/juvix#2205 - will syntax errors make the code disappear when formatting? Even after that PR is merged? Do we need to change something in the format command to help?

The way it currently works, in case of the error, it will not change the content of the file, but will just display the error we got from the command. So with the error case, no changes are required by the vscode extension 🙂
