instance of Fn::GetAtt references undefined resource

Hi, after updating from 1.9.3 to 1.10.0 i started to receive this following error on my deploys:

 Error: The CloudFormation template is invalid: Template error: instance of Fn::GetAtt references undefined resource QueryUnderscoreConversationLambdaFunction

After reverting back to 1.9.3 it returns to normal.
Let me know if any more info is needed, not quite sure on which detail I can contribute to solve this error!

Thanks!

We have been reducing for a repeatable use case for weeks already. Trying commit by commit, it is cycling back and forth between this bug and circular dependency.

I'll try to point my project to specific commits to see if I can found which one is causing it

@Negan1911
I think these changes are causing the issues:
https://github.com/dougmoscrop/serverless-plugin-split-stacks/blob/master/lib/utils.js#L243
https://github.com/dougmoscrop/serverless-plugin-split-stacks/blob/master/lib/utils.js#L248

context for ref: #147 (comment)

@mnickkk I want to fix this in my fork and possibly make a PR if none if the release branches here fixes the issue, but I don't think I understand the underlying cause enough.

Is cloneDeep doing its job correctly?

My current best guess is that cloneDeep does not resolves object references for migration utilities to know that when target resources are eventually allocated into different stacks, they should be hoisted into <Output> and <Paramaters> at root stack.
