Finish removal of organization short name

[cielf]

Summary

Some time ago, we removed short name from the URLs. Finish removing it.

Why?

Keeping things clean!
(Short name was probably used to link the old partnerbase and diaperbase dbs. We combined them a couple of years ago)

Details

1/ it looks like current_organization uses short_name. Figure out a way around that.
1/ Remove short name from the admin and bank views of the organization, and the admin edit
2/ Anything else that is revealed with a search for short name (anywhere we use short_name, we should be able to engineer to use id instead)
4/ write a migration to drop the short_name from organization

Criteria for completion

• changes as described
• all tests addressed for the changes
• check if the user guide mentions short name (as opposed to short_name for the rest of the code). If it does, make the appropiate adjustments.
