Title: [WIP] Speed up tests

* Install virtualenv from an archive instead of git which is faster (~40s)
* Install setuptools and pip in a single subprocess from Wheel instead of setuptools from wheel in one subprocess, then copy + ``setup.py develop`` in an additional subprocess. (~750s but with test failures).
