[desktop] Handle autoUpdate errors

Summary:
We want to handle autoUpdate errors (in particular error about no network connection). If we add a listener to an error event electron no longer displays the native alert with the error. Now we can just log it and restart the update schedule.

This replaces D6683 and D6684 as it's a much better solution.

Test Plan: Run the app, turn of internet connection. Check if the error is displayed and the app continues to check for updates.
