Don't cache invalid serialized Physical Web URLs

Don't cache invalid serialized Physical Web URLs

Currently, when the UrlManager starts, it deserializes our stored
UrlInfos and attempts to gracefully fail if one cannot be deserialized.
However, the URL the info corresponds to may be contained in some still
existent cache.  This change makes sure that only URLs that are
properly deserialized are stored.
