Does not work for bs-platform 7.3.1 yet

bs-platform: 7.3.1
reason-vscode: 1.7.8
OS: MacOS 10.15.4

If a file contains no errors, compilation works just fine. If there are some error, plugin does not highlight them, file silently does not compile.

I can attach full /node_modules/.lsp/debug.log if needed.

I can see some signs of found error in the debug.log.
```

On latest official version bs-platform@7.2.2 works as expected. I'll stick with it for now.

Reproduce the failure with bs-platform 7.3.1 and reason-vscode 1.7.8 on the reported MacOS setup, using the components/TopPanel.re example and /node_modules/.lsp/debug.log. Compare the behavior with bs-platform 7.2.2; done means compilation errors are highlighted instead of the file failing silently.
