Is this a bug report or a feature request?

• [X] Bug Report
• [ ] Feature Request

Please provide the steps to reproduce the issue [Bug Report only]

Sample repository is in [email protected]:sangb-han/angv16_multi.git .

Create project like followings

> ng new angv16_multi --no-create-application
> cd angv16_multi
> ng g project sample_app
> ng g library sample 

After that, jest has been configured like in angular blog.

If I ran in workspace with single project, there was no problem. But in workspace with multiple project, test with jest failed.

Please provide the expected behavior vs the actual behavior you encountered [Bug Report only]

All test run successfully.

Please provide a screenshot if possible [Bug Report only]
