This PR fixes the issue where user providers rely on just the UnsupportedUserException from `refreshUser()`, causing a flow where users are wrongfully re-authenticated.
There's one issue where `refreshUser()` can do far more sophisticated checks on the user class, which it will never reach if the class is not supported. As far as I know it was never intended to support instances that are rejected by `supportsClass()`, though people could've implemented this (by accident). So the question is more if we should add a BC layer for this; for example:
```php
try {
$refreshedUser = $provider->refreshUser($user);
$newToken = clone $token;
$newToken->setUser($refreshedUser);
if (!$provider->supportsClass($userClass)) {
if ($this->shouldCheckSupportsClass) {
continue;
}
// have to think of a proper deprecation here for 6.0
@trigger_error('Provider %s does not support user class %s via supportsClass() while it does support it via refreshUser .. please set option X and fix %s::supportsUser() ', E_USER_DEPRECATED);
}
```
This would prevent behavior from breaking but also means we can't fix this on anything less than 5.1.
