Consistently set AuthenticationEventPublisher in AuthenticationManage…

…rBuilder

Prior to this, the HttpSecurity bean was not consistent with WebSecurityConfigurerAdapter's HttpSecurity because it did not setup a default AuthenticationEventPublisher. This also fixes a problem where the AuthenticationEventPublisher bean would only be considered if there was a UserDetailsService

Closes gh-11449
Closes gh-11726
