We seem to be getting an error when the cli attempt to update plugins.

We seem to be getting a new error in the cli that seems to be related to this change:

e0b5e95

We are seeing cases in the sfdx-cli when parent.children is undefined and this
results in the following error:

Installing dependencies for /Volumes/CaseAware/force-com-toolbelt... ⢿
(node:70974) TypeError Plugin: cli-engine: Cannot read property 'push' of undefined
module: @oclif/config@1.10.3
task: loadPlugins

(node:70974) TypeError Plugin: cli-engine: Cannot read property 'push' of undefined
module: @oclif/config@1.10.3
task: loadPlugins
plugin: cli-engine
root: /Users/tnoonan/tmp/node_modules/cli-engine

Steps:

1. Completely remove sfdx from the system:

sudo rm -rf /usr/local/sfdx
sudo rm -rf /usr/local/lib/sfdx
sudo rm -rf /usr/local/bin/sfdx
sudo rm -rf ~/.local/share/sfdx ~/.config/sfdx ~/.cache/sfdx
sudo rm -rf ~/Library/Caches/sfdx

2. Install sfdx

npm install sfdx-cli

3. Install a plugin
   node_modules/sfdx-cli/bin/run plugins:install salesforcedx@pre-release

This results in the error above.

This seems to fix the issue for us.
