Use response from calls to insertRecords in tests (datatypes P-W)

Most tests assert the initial record passed into insertRecords.
Since we mutate the inserted records to add the uuid this
currently works, but in a follow up change we'll update the
insertRecords API so it no longer mutates the metadata. This
requires changes to most of the cts tests.
