[FIX] *: fix duplicate palette crashing render in theme tab

*: theme_anelusia, theme_avantgarde, theme_bookstore, theme_buzzy,
   theme_real_estate, theme_treehouse

Since website refactor [1], a silent error would occur while rendering
the theme tab, because of the use of `t-foreach`, leading to nothing
being displayed depending of the theme.

This was caused by a duplicate key in the
`$o-selected-color-palettes-names` scss variable, added by some theme,
which would make the `t-foreach` crash in `website.ThemeColorsOption`.

Steps to reproduce:
- Create a website using any of the above themes, through the wizard
- Enter edit mode
- Click on theme tab
- Nothing is rendered
