Description

In the settings view, under "Packages," the "core packages" list is sometimes empty with the new Electron 9 build of Atom.

Steps to Reproduce

1. Go in to the menu and visit "Settings" or "Preferences"
2. Visit the "Packages" view

Expected behavior:

All of the core packages are always listed.

Actual behavior:

None of the core packages are listed.

Reproduces how often:

Linux: 100% of the time, I think.

macOS: Not sure if it happens on macOS; Having trouble reproducing it on macOS.

Windows: Also not able to reproduce it on Windows at this time.

Versions

Atom    : 1.57.0-dev-42f24335d
Electron: 9.4.4
Chrome  : 83.0.4103.122
Node    : 12.14.1

apm  2.5.2
npm  6.14.8
node 12.4.0
atom 1.57.0-dev
python 
git 2.25.1

Additional Information

This might be only a Linux thing.

(I vaguely recall something about it maybe happening in Dev Mode, or when no community packages are installed, but maybe that was for older builds from before the Electron 9 PR finished; Right now I can only reproduce it on Linux, and it's 100% of the time for me on Linux, regardless of any other factors.)
