Workaround issue with creating a module from command line

I'm not quite sure why, but when creating a new module using
the scaffolding command, the FileChangeMonitor doesn't detect a new
directory has been added in "~/Modules". Added an explicit call to
the OrchardHost to force reloading of extensions.
