remove the function and use an exception block instead

This patch keeps in sync the DBs of the bodega-server and discourse.

It syncs,

a. the user accounts*
b. for each asset that has a partner with id > 1000 it create a new forum which has a topic and a post

* there is a default account for the discourse
username: forumadmin
password: password

How to test it,

* git clone https://github.com/terietor/discourse.git
* cd discourse
* git checkout bodega
* https://github.com/terietor/discourse/blob/master/docs/DEVELOPER-ADVANCED.md
* cd bodega-server/server
* make sql && make test-sql (your bodega user must be a superuser in order to enable the dblink extention)
* then go back to discourse and do `bundle exec rails s`
* go to localhost:3000
