[BUGFIX] Reinitialize PageRenderer after deserialization

Do not swap the global singleton instance, as
that would only update new classes that are
retrived though GeneralUtlity::makeInstance).
Existing ones (cached in already initialized
classes, or initialized via the symfony DI container
would not be updated).
