Rob Winch 9d543ce4d1 Allow custom ReactiveAuthenticationManager for basic and form auth
Prior to this change, "HttpBasicSpec#authenticationManager" and
"FormLoginSpec#authenticationManager" were always overridden by
"ServerHttpSecurity#authenticationManager".

This commit makes sure override only happens when custom authentication
manager was not specified.
