Bad formatting even though config is correct

[andrecasal]

Summary

Prettier is logging the correct config but formatting with another (default?) one.

Github Repository to Reproduce Issue

N.A.

Steps To Reproduce:

1. Install Consider adding instructions on how to have VS Code use these same configs to format files. epicweb-dev/config#43
2. Enable Prettier's extension logs by adding "prettier.enableDebugLogs": true, to your VS Code's settings.json file

Expected result

The file should have been formatted according to the config in the log.

Actual result

The file was formatted with some other rules (the default rules?).

["INFO" - 7:51:47 PM] Formatting completed in 51ms.

As you can see from the logs, semi-colons are supposed to be removed (among other rules), but instead they are added, when saving the file with formatOnSave (or manually selecting "Format Document" from VS Code's command palette).
