Stencil: Running tests throws error

Describe the bug Running tests throws the following error:

> nx run my-lib:test 
[25:42.9]  testing spec files
[25:42.9]  jest args: --projectType=library --tsConfig=libs/my-lib/tsconfig.lib.json
           --configPath=libs/my-lib/stencil.config.ts --outputPath=dist/libs/my-lib --spec --max-workers=8

[ ERROR ]  runJest: TypeError: Class extends value #<Object> is not a constructor or null

To Reproduce

1. Create new library nx g @nxext/stencil:lib my-lib
2. Run tests nx test my-lib

Expected behavior Run tests without error.

I’ll close this @SebastianSchenk. I added your fix for the jest-config package to the init generator until it’s fixed in stencil side.

Hopefully, that’s all obsolete after Stencil supports Jest 27 natively
