Re-initialising Orchard Core database

Question

Up until now in order to re-initialise the Orchard CMS I was removing the app_data/Site folder which resulted in Orchard showing the setup page. For some reason this is no longer working and I get the following error

System.NullReferenceException: Object reference not set to an instance of an object.

This also happens if I simply remove the settings.txt file

My question is what is the best way to force Orchard to show the setup page. I'm running 1.0.0-beta3-70136

The error was caused by my injection of the Orchard ISiteService class. Not sure why but I removed the DI and the error went away
