When opening a saved search or a bookmarked search from the places sidebar, the search bar is shown. However the state of the toolbar' search button is _not_ updated accordingly. This results in:

- to close the search bar, the user has to click the search button twice. this is both annoying and confusing.

- when opening a saved search /home/foo/something.savedSearch, the path bar shows the whole path /home/foo. However, clicking e.g. /home in the path bar results in home being shown with the search bar still on.

Attached is a patch that fixes both issues (AFAICS) by changing NautilusToolbar::toolbar_update_appearance () to also update the state of the search button appropriately.
