Remember me doesn't work correctly with an ajax request

* User Logged in with Remember Me
* Session Times out (usually after 30 minutes)
* Left browser window open and proceeds to make Ajax request

Request returns a status code 302 with a redirect to '/login/ajaxSuccess' or whatever is defined as the ajaxSuccessUrl

```
authenticationSuccessHandler(AjaxAwareAuthenticationSuccessHandler) {
requestCache = ref('requestCache')
defaultTargetUrl = '/'
alwaysUseDefaultTargetUrl = false
targetUrlParameter = 'spring-security-redirect'
ajaxSuccessUrl = '/login/ajaxSuccess'
useReferer = false
redirectStrategy = ref('redirectStrategy')
}
```

Correct behavior should be to process the request as normal as the user is already logged in from RemeberMeServices
