Bug 37246: Use the same dropdown for filtering and editing/adding budgets

This patch removes a second fetch of budgets form the db, and clones the dropdown in the template
as we will only ever be displaying one of them at a time.

The JS is moved to fire for both operations.

To test:
 1 - Create an active and inactive budget in acquisitions
 2 - Add funs to both
 3 - Visit - Acquisitions -> Suggestions
 4 - Click 'Acquisition information' under filters on the left
 5 - Note all funds are showing
 6 - Apply patch
 7 - Reload
 8 - Note you only see active budgets
 9 - Check the box to show inactive, verify they show
10 - Filter by an inactive budget
11 - Confirm selection remains
12 - Add a suggestion and verify budget dropdown works
13 - Edit the suggestion and verify budget dropdown works
