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 --------- Co-authored-by: Fabio Pliger <fpliger@anaconda.com>
