[Webpack] Compilation error fix

[laemtl]

Address an issue that prevents webpack and the post-install script to run when patch SQL/New_patches/2022-12-05-AddVizConfig.sql is not applied.

Now the errors are caught and a warning is printed on the screen.

The same fix was needed for npm-postinstall.js as well. It's done.
