fix(e2e): stabilize search history multi-item test

Re-navigate to the home page before each search in
test_e2e_search_bar_user_search_history_multiple_items so the header
search bar picks up a fresh v-model binding between searches. Without
this, consecutive searches from the /search results page left the input
in a stale state and the URL never transitioned to the next query.
