[IMP] test_themes: adapt to website_preview client action

This commit removes the tooltips shown when hovering over a theme in
the website switcher dropdown. This feature will be reimplemented later,
patching the WebsiteSwitcherSystray component.

It also adapts the ?fw= url parameter to force a website id during the
tours.
