IQF compliant queries in migration tests

[sean-brandenburg]

What, How & Why?

Device sync is enabling indexed queryable fields in PBS->QBS migrations which means that there are limitations on the types of queries that a QBS client is able to make after the migration (See Here)

This change fixes some non compliant queries in migration tests

realm_id = partition1 OR realm_id = partition2 -> realm_id = partition2
truepredicate -> realm_id = partition2
