Since all other databases have prefix "Microsoft.eShopOnContainers.Services" we need to fix IdentityDb namespace as well.

@slsniffer please update your forked branch with dotnet-architecture/eShopOnContainers, as its 14 commits behind.
I need to test your updated branch changes, so that we can merge the PR.
