Fix testRetentionWhileSnapshotInProgress (#48219)
This test could fail for two reasons, both should be fixed by this PR:

1) It hit a timeout for an `assertBusy`. This commit increases the
timeout for that `assertBusy`.

2) The snapshot that was supposed to be blocked could, in fact, be
successful. This is because a previous snapshot had been successfully
been taken, and no new data had been added between the two snapshots.
This means that no new segment files needed to be written for the new
snapshot, so the block on data files was never triggered. This commit
changes two things: First, it indexes some new data before taking the
second snapshot (the one that needs to be blocked), and second,
checks to ensure that the block is actually hit before continuing
with the test.
