subsequent searches expand first row in search results

[Michael Vogt]

When searching sometimes the first row is expaned but not selected, this loos rather odd. To reproduce:
- open software-center
- search for "foo"
- select one of the search results
- search for "bar"

The first row in the search is expanded but not selected. It should not expand.

Disabling _update_selected_row fixes it, so its something to do with that:

It appears the issue is that clear_model() needs to disconnect the view to avoid a whole bunch of "cursor_changed" signals.
