[Security]: Don't let falsy usernames slip through impersonation

When you try to impersonate users with a falsy username, `SwitchUserListener::handle()` would `return;` and impersonation would fail.

I'm using a third party OAuth provider that allows users to change their usernames with no guaranteed protection against re-use. To overcome that issue, I implemented `UserLoaderInterface::loadUserByUsername()` and query by a `providerId`.

After loading development fixtures, One user has `0` as it's `providerId`.
