Subject: [PATCH] fix: error calling .startsWith on null mime_type

According to the package documentation: https://www.npmjs.com/package/mime
> null is returned in cases where an extension is not detected or recognized

This call to `.startsWith()` was causing an exception to be thrown upon
right-clicking files without an extension, making it impossible to fix
them.
