Support multiple RegisterTypes calls on one IBuilder instance

[erictuvesson]

Currently the second RegisterTypes call overrides the previous call as it's saved as an action in the builder.

new ServerBuilder()
    .RegisterTypes(serviceCollection =>
    {
        // Never called
    })
    .RegisterTypes(serviceCollection =>
    {
        // Called
    })

Would be nice if it was possible to call it multiple times or that it alerted that it is already set.
