Crashes on syntax errors

[hawkins]

Currently, prettier.format returns an error when invalid syntax is parsed. This crashes the plugin.

Fixing this should be as simple as adding a try-catch around that block.

It would be great if we could optionally specify a flag, such as warn: True that will use console.warn to warn the user of compilation errors too, instead of just silently failing.

Looks like this is indeed fixed now. Sweet! 🥇 @esganzerla
