Match Guava's null-rejection in the adapter's asMap().replace

The facade's asMap().replace(K, V, V) short-circuited on the old-value
guard first, so replace(null, null, v) and replace(k, null, null)
returned false where Guava throws. Guava's LocalCache.replace checks
the key and new value for null before considering the old value; do the
same so the null corners reject rather than silently no-op. The
existing null-old-value case (replace(k, null, v) -> false) is
unchanged. Pinned by a CaffeinatedGuavaTest parity case run against
both the adapter and a real Guava cache.
