Prior to this change, we'd store the GMPStorage records for private browsing sessions in the GMPStorageParent. The problem with this is that they only have a lifespan matching their corresponding GMPParent. This means that if a GMP stores something in a PB session, and the GMP is shutdown and then re-created, we are likely to loose the stored data. This could mean that the PB session gets results it doesn't expect, and thus expose a way for PB mode to be detected.
