Fresh clone of repo on master does not build Swagger Issue

[Alik2015]

When cloning repo or pulling new changes the project IdServer.Startup no longer builds with the following errors.

'IServiceCollection' does not contain a definition for 'AddSwaggerGen' and no accessible extension method 'AddSwaggerGen' accepting a first argument of type 'IServiceCollection' could be found
'IdentityServerConfiguration' does not contain a definition for 'ForceHttps' and no accessible extension method 'ForceHttps' accepting a first argument of type 'IdentityServerConfiguration'

Oops! The build has been fixed in the master branch.
