[dataplane] reset ActiveStream::streamInfo().route() when clearRouteCache()

Title: reset ActiveStream::streamInfo().route() when clearRouteCache()

Description: There is a gap between the ActiveStreamFilterBase::clearRouteCache and ActiveStreamFilterBase::streamInfo()::route():

whenever we call clearRouteCache(), the {en,de}codercallback.route() ONLY!, the streamInfo().route() is NOT updated.

The "new" route() on {en,de}codercallback will be reset when we refreshCachedRoute(), by either explicitly calling it, or calling {en,de}codercallback.route().

So after a clearCachedRoute(), the route() on streamInfo is "stale" and will be out-of-date until refreshCachedRoute() is called.

we should explicitly clear/reset streamINfo()::route_ in clearRouteCache()
