Fixing `dotnet ef database update` 

Currently it is impossible to create database for the chat sample - `dotnet ef` commands fail with: "No parameterless constructor was found on 'ApplicationDbContext'. Either add a parameterless constructor to 'Application
DbContext' or add an implementation of 'IDbContextFactory<ApplicationDbContext>' in the same assembly as 'ApplicationDbC
ontext'." - adding IDbContextFactory implementation to fix this

Also disabling Redis presence in favor of in-memory presence
