Packages installed via PackagesInstaller are not "fully" installed #60
Description
Packages installed via \Youwe\TestingSuite\Composer\Installer\PackagesInstaller are not fully installed by Composer in the sense that the following files
- vendor/composer/installed.json
- vendor/composer/installed.php
and also the autoloader do not recognize the newly installed package (or package version)
This should be debugged and fixed. Might be that the new composer internally has a new flow which doesn't fully allow installing new packages during a running install or so - or something else. However, it is causing problems with fresh installations so should be resolved.
