Hyper crashes whilst idle after update

• I am on the latest Hyper.app version
• I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: Mac OS 10.12.6 (16G29)
• Hyper.app version: 1.4.2 (Failed to update to 1.4.3)
• Link of a Gist with the contents of your .hyper.js: https://gist.github.com/CodeTheory/a3a770ed8bfb593e87f0dbeb378b737f
• Relevant information from devtools (CMD+ALT+I on Mac OS, CTRL+SHIFT+I elsewhere): N/A
• The issue is reproducible in vanilla Hyper.app: Couldn't test on Vanilla since the steps to reproduce are odd

Issue

Here's how I got this:

• Opened hyper yesterday, idle until this morning
• Update notification for 1.4.3, clicked to restart
• Didn't open Hyper again and about 30 minutes later, get that error since the icon was bouncing I noticed it
• Hyper didn't update to 1.4.3

A JavaScript error occurred in the main process
Uncaught Exception:

Start with notify.js:36 and trace the error through plugins.js:86 and plugins/install.js:28-43, using the reported failed update and idle sequence as context. Determine why the main process handles the update failure after the relevant object is destroyed; done means the sequence no longer produces the reported uncaught "Object has been destroyed" error.
