[FIX] theme_odoo_experts: remove unused configurator snippets

Currently, an error occurs while importing an 'Experts' theme template.

Steps to produce:

- Install the 'website' module.
- Build one website, try to switch its theme to the 'Experts' theme.

ValueError:
External ID not found in the system: website.configurator_s_picture

When switching a website theme to the 'Experts' theme, an error occurs
during importing their XML definition because their parent template does
not exist. To resolve this issue we can remove this template.

Indeed, that configurator snippet override was not needed anymore since
the 'Experts' theme was not using that specific snippet for their
configurator pages anymore. The error went unnoticed because on runbot
all themes are installed, and at least one of them was using that
specific snippet in a configurator page. This will be improved.

See [1] with the same kind of issue.
