Steps to Reproduce:

1. Open new settings editor, search for "emmet extension"
2. Emmet: Extensions Path is a setting that takes path to a directory. Start typing a path

Since we auto-save in 100ms, the config change event is fired for almost every other character typed, which results in validation checks from the emmet extension resulting in a series of error notifications.

There might be other extensions in the marketplace that do such validations after listening the config change event.
