ProviderManager.copyDetails Changes Authentication to new Type

[rwinch]

Currently, if the Authentication.getDetails() is non-null on the input to ProviderManager, then the ProviderManager.copyDetails method will invoke Authentication.toBuilder() method to set the details. This is fine if an Authentication implements toBuilder, but it unnecessarily breaks custom Authentication types that do not implement toBuilder.

We should revert the behavior to previous versions of Spring Security which invoke AbstractAuthenticationToken.setDetails.
