Enabling/disabling features or running a migration update fails with Orchard.OpenId (even if disabled) not being able to resolve one of the dependencies of Microsoft.Owin.Security, because it (and some other projects) use version 4.1.1 of Microsoft.Owin.Host.SystemWeb and Microsoft.Owin.Security, while the other Owin libraries are on version 4.2.2.

Fortunately, fixing it is as simple as a search and replace of the string "4.1.1" to "4.2.2".
