@nrwl/workspace:move resets standaloneConfig project, deletes project.json

Current Behavior

When I rename a standaloneConfig package using @nrwl/workspace:move, it deletes the project.json file and moves the configuration back to workspace.json, resetting the standaloneConfig:

npm run nx -- g @nrwl/workspace:move --projectName nx-debug --destination nx-debug-app

Expected Behavior

When I run the above command, I would expect the project.json file to be updated, not to be deleted, and I would expect the package to remain a standalone project.

While I have larger workspaces that are not exhibiting this behavior (move works for them), they use the same version of nx (12.6.2); however, they were created with earlier versions of nx and migrated to latest, so it is unclear whether or not this is a regression.

Steps to Reproduce

This repo is the result of creating a new workspace, converting to standalongConfig, and running the above command: https://github.com/JoshuaCWebDeveloper/deubg-nx-move-standalone-001
