Bug 33014: (QA follow-up) Move filters before navigation in sidebar

This follows the pattern we have on other pages like suggestions,
tags and invoices by putting the filters on top of the navigation
in the sidebar on the left.

To test:
* Search subscriptions
* Verify that on the left it's navigation - search options
* Apply patch
* Verify it's now: search options - navigation
