Incorrect install directory

Some projects install in the `packages/projects/projects` root folder when they should be installed one layer deeper into the `ir-engine` and possibly the `theinfinitereality` folder.

Projects do install correctly following the command structure from the [pro repo](https://github.com/theinfinitereality/irpro-platform/blob/dev/readme.md).
```
npm run clone-project -- --url {git https URL}
```

An audit of the manifests may also be in order to be sure all projects are up-to-date and relevant.

Start with the `npm run clone-project -- --url {git https URL}` entry point and inspect how project manifests determine the install path. Verify the expected `ir-engine` and possibly `theinfinitereality` nesting, then review the manifests for outdated or irrelevant projects; done means cloning places projects correctly and the manifest set is current.
