test(providers): align preset selector tests with official-first ordering

The official-first/prime-partner sort changed Original mode order, but the
selector tests still asserted the old raw array order. Update the three
stale assertions and add a dedicated case covering the prime-partner group
and the exclusivity rule (an official preset also flagged primePartner
stays only in the official group).
