[FIX] website: broken assets test on multi website

The `test_01_multi_domain_assets_generation` was introduced in PR [1].
But afterward, the commit [2] introduced a unique constraint on the
`domain` field. With this additional constraint, this test broke when
run with multiple existing websites as it assigns the same domain for
each of them.

This commit made the dummy domain assigned in this test non-unique,
which doesn't alter the original meaning of the test but, allows to run
it with multiple existing websites.
