Particle commands hang without internet connection when update is attempted

[zacnelson]

When executing particle commands, if an update is attempted, then the command hangs for 2 minutes. I've encountered this issue now on WSL and on a Raspberry Pi so it might be contained to Linux, but I'm not sure. I was unable to recreate this bug in Windows Command Prompt.

To recreate the issue, I disconnect my laptop or Pi from WiFi, then force updates with: particle --force-update-check. I can see that the initial update check times out after 3 seconds per this line in settings.js but I'm not sure why the rest hangs for the remaining 2 minutes. It'll print out the help command list and then hang.

Update: In Windows Command Prompt, particle --force-update-check without wifi takes a total of 13 seconds to complete, 3 of which are the initial cli update timeout. The remaining 10 seconds are just waiting after the help manual is printed to the console.
