[FIX] test_themes: run configurator standalone test under mocked request

Commit [1] copies configurator pages during the flow. When the
standalone test leaves website_id in the context, that copy now tries
to create generic views with a website-scoped environment and hits the
ir.ui.view guard. Running the configurator inside MockRequest mimics the
real HTTP context (request-driven website, no forced id on the ORM), so
the copy succeeds and the test passes again.
