pgsql: Remove duplicated log related to slot creation in pg_createsubsc

Remove duplicated log related to slot creation in pg_createsubscriber

The creation of a replication slot done in a specific database on a
publisher was logged twice, with the second log not mentioning the
database where the slot creation happened. This commit removes the
information logged after a slot has been successfully created, moving
the information about the publisher from the second to the first log.
Note that failing a slot creation is also logged, so there is no loss of
information.
