Unhandled rejection when using quokka.js extension

Unhandled rejection when using quokka.js extension
When using the quokka.js extensions I get a Unhandled rejection error when the new file opens and each time I type a character.

To Reproduce
Steps to reproduce the behavior:

1. Install Quokka.js
2. ctrl+shift+p -> Quokka.js: New JavaScript File
3. See error

Unhandled rejection. Promise [object Promise]. Reason: AssertionError [ERR_ASSERTION]: { uri: [Getter], fileName: [Getter], isUntitled: [Getter], languageId: [Getter], version: [Getter], isClosed: [Getter] == { uri: [Getter], fileName: [Getter], isUntitled: [Getter], languageId: [Getter], version: [Getter], isClosed: [Getter].

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.0.0
• VSCode version: 1.30.1
• OS: Fedoras 29

Additional context
Everything seems to work fine, it just keeps throwing the error.

See this for context around these error messages. #3332 (comment)

In terms of this error, we are subscribing to I handled rejections on the process. My theory is that all the extensions are run on the same process so with the extension that you installed, it's not handling this promise rejection and therefore we are displaying it as an error. I think the fix here is to remove the logging of unahndled rejections at the process level. There shouldn't be any negative side effects with this message.

Just want to add on here that I'm also seeing this with errors from ESlint, such as those that are thrown by the plugin when it can't parse your code (such as while you're typing)

Yah. We should get rid of this. Obviously doesn't make sense for us to log other extensions errors. Lol. Contributions welcome if somebody wants to remove this piece of code.
