Add logging to module published trigger

On alpha, all the problems from Connexions/cnx-upgrade#36 are still there.  The uuid changes when you republish an existing module, the major and minor versions are not set.

I tried inserting the module that I found on `/var/log/postgresql/postgresql-9.3-main.log` on alpha into my local db:

```
INSERT INTO modules                                                                                      
                  (moduleid, portal_type, version, name, created, revised, authors, maintainers, licensors,  abstractid, stateid, licenseid, doctype, submitter, submitlog, language, parent)
                VALUES
                (
                 'm47641',
                 'Module',
                 '1.1',
                 'HTML Publishing Test 2 12-13-2013',
                 '2013-12-14T01:57:20Z',
                 '2013-12-14T01:58:24Z',
                 ARRAY ['ew2'],
                 ARRAY ['ew2'],
                 ARRAY ['ew2'],
                 1,
                 NULL,
                 7,
                 '',
                 'ew2',
                 'Created module',
                 'en',
                 null
                );
```

It has uuid `18da04bd-b3dc-4568-a45f-3b11b00a01aa`, major version `1` and minor version `NULL`.

I tried publishing the same module again:
```
INSERT INTO modules                                                                                                     (moduleid, portal_type, version, name, created, revised, authors, maintainers, licensors,  abstractid, stateid, licenseid, doctype, submitter, submitlog, language, parent)
        VALUES
        (
         'm47641',
         'Module',
         '1.2',
         'HTML Publishing Test 2 12-13-2013',
         '2013-12-14T01:57:20Z',
         '2013-12-14T02:58:24Z',
         ARRAY ['ew2'],
         ARRAY ['ew2'],
         ARRAY ['ew2'],
         1,
         NULL,
         7,
         '',
         'ew2',
         'Created module',
         'en',
         null
        );
```

It has the same uuid `18da04bd-b3dc-4568-a45f-3b11b00a01aa`, major version `2` and minor version `NULL`.

So it works on my local machine but not on alpha.

I'm pretty sure the code is working, so what I'm doing in this PR is to just add some logging to see if there's anything unexpected happening.
