Adopt formatOnSave changes

[jrieken]

Since version 1.6 VS Code has a format on save option. It works by calling the registered formatting provider for the language in question and most importantly it happens before the file is saved to disk, not causing additional fs writes and event cascades.

Please adopt this code code by either removing it and trusting the new editor.formatOnSave-setting or by using the new onWillSaveTextDocument-event.

See https://code.visualstudio.com/updates#_format-on-save, microsoft/vscode#12449, and microsoft/vscode#239 for more details
