Fix cache look-up failures while applying changes in logical replication. While building a new attrmap which maps partition attribute numbers to remoterel's, we incorrectly update the map for dropped column attributes. Later, it caused cache look-up failure when we tried to use the map to fetch the information about attributes.
This also fixes the partition map cache invalidation which was using the wrong type cast to fetch the entry. We were using stale partition map entry after invalidation which leads to the assertion or cache look-up failure.
