Fix logic for when entire cache is invalidated

Browse Source 
Sometimes postgres wants to invalidate the entire cache. In this case it
send a cache invalidation message with relid == InvalidOid. This should
invalidate all the caches. Previously, it did not effect the cache of
the extension state. This fixes that problem and creates one cache reset
code path for both extension dropping and whole-cache reset, cleaning
up some of the logic in the process.
