[android] Fixed crash during access to C++ framework place page object while it's not intitialized. It may happen when the app was killed/dumped by OS when PP is opened (launched by incoming intent or deeplin) and then core doesn't have place page info and synchronization between platform and C++ framework is broken. So, we don't restore place page info from java map object and it's by design for a while.
