pgsql: Set replication origin when decoding commit records.

Set replication origin when decoding commit records.

By accident the replication origin was not set properly in
DecodeCommit(). That's bad because the origin is passed to the output
plugins origin filter, and accessible from the output plugin via
ReorderBufferTXN->origin_id.  Accessing the origin of individual changes
worked before the fix, which is why this wasn't notices earlier.
