Dash - Navigating lens categories with Shift+Tab does not work for filter

[Sami Jaktholm]

Steps to reproduce:
1. Open Dash
2. Go to Apps lens
4. Press Shift + Tab and Filters is highlighted (or the Sources item if filters are visible)
5. Release Shift + Tab

What should happen:
- The Filters remain highlighted and you can expand the filters with Enter.

What happens:
- The Filters lose focus and nothing happens when Enter is pressed.

Why this happens:
- Dash focuses the search box on Shift-up.

This also happens with unity-5.8.0-0ubuntu2 from the main repos so it's not a regression in the latest RC from Unity-team PPA.

I think that's an outdated test description. AFAIK it's supposed to be Ctrl-Tab for the next lens and Shift-Ctrl-Tab for the previous lens.

Hernando, he is not talking about switching lens but rather switching between the different categories in the same lens. When press Shift+Tab, it goes to the filter but on releasing Shift+Tab the highlight is no longer on the filter.
