Finish removal of Organization short name - Part 1

[jp524]

Related to #5167

Description

I removed the organization's short name from URLs last year in #4331. We now want to remove the column from the Organization table and ensure that everything still works.

This PR is best reviewed commit by commit.

Checklist from issue:

• it looks like current_organization uses short_name. Figure out a way around that.
  -> I introduced the param organization_id where required
• Remove short name from the admin and bank views of the organization, and the admin edit
• 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)
  -> There were quite a few spots were organization_name was used but no longer required. I cleaned that up as well
• write a migration to drop the short_name from organization
  -> Removing a column requires the migration needs to be to done in multiple steps based on the Strong Migrations docs. I've done the first step (ignoring the column) in this PR. Finish removal of Organization short name - Part 2 #5187 contains the migration and can only be ran after this PR has been deployed
• 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.

Type of change

• New feature (non-breaking change which adds functionality)
• Documentation update

@dorner -- I think this one is mostly in your wheelhouse -- I'll need to do a sanity check once you've ok'd it just to make sure I cant break the current organization stuff.
