Commented Issue: Can't enable a New Project Web App after Running Installer [22161]

Not sure where the bug is, but I found that when running the Installer you cannot enable the pwasite feature. Creating the Farm from scratch does allow this. It fails on "Enable-SPFeature pwasite -URL http://projects.portal.contoso.com/sites/pwa1" stating that the "The Project Content Database extension has not been provisioned for this content database."

OK, I have some more information from the ULS Logs. Maybe its a bug.
