next integration tests (#1712)

* move integration tests pyscriptjs/tests/integration ->pyscript.core/tests/integration

* add information in regards to how to run integration tests to README

* fix fake server build paths

* fix paths to build and run tests. The change of path before integration tests is a glitch maybe due to pytest cache?

* remove test files created by mistake

* update readme with latest changes
