Catalog page - department filter doesn't stay when clicking on "Programs" tab

[rachellougee]

Noticed this bug when reviewing #1914

Expected Behavior

When clicking on "Programs" tab with a specific department, I would expect the department filter stays.
If it doesn't stay, then the result should be accurate on new catalog page

Current Behavior

When clicking on "Programs" tab with a specific department, the filter got reset to "All departments" but result is still for that specific department.

Steps to Reproduce

1. Go to https://rc.mitxonline.mit.edu/catalog/
2. Click on Economics department, you should see

3. Click on Programs tab, it displays two programs with "All Departments" instead of "Economics" selected

4. Click on "All Departments", it now shows 11 programs (conflicts with above result)
