Ionic-cli: ionic cordova resources command returns 410 error (CLI v3.20.0 )

[zaarheed]

Description:
I updated to Ionic CLI v3.20.0 and was unable to upload a build to the App Store via XCode due to alpha channels in my icons.

I ran ionic cordova resources --force and ionic cordova resources ios and both return the following error after prompting me for my Ionic username and password:

Request: POST https://api.ionic.io/login
Response: 410
Body: 
{}

Steps to Reproduce:

1. Run ionic cordova resources ios.
2. Enter username when prompted.
3. Enter password when prompted.
4. Error message appears.

Output:

$ ionic cordova resources ios --verbose

@zuperm4n Try ionic config set -g backend pro and then ionic login again. You are attempting to login to the old Ionic Cloud backend. This is a bit confusing, my apologies. I need to get CLI 4 out which removes that backend.
