[FIX] theme_*: fix breadcrumb color

*: anelusia, anelusia, enark, kiddo, loftspace, notes

- Install Website e-commerce.
- Select the "Kea" theme for your website.
- Go to the "/shop" page.
- Click on "Desks" category to go to the "/shop/category/desks-1" page.
- Click on edit to enter edit mode.
- Click on the "theme" tab.
- Change the website background color to "black".
- Bug: The breadcrumb has an ugly white background instead of no
background color, as in the "default" theme. Also, the "active"
breadcrumb item is hidden due to white text on a white background.

This commit removes the white background from the breadcrumb for all
themes that use it. This ensures the same appearance as other themes.
