In tests, await an LSN no later than the recovery target.

Otherwise, the test fails with "Timed out while waiting for standby to
catch up".  This happened rarely, perhaps only when autovacuum wrote WAL
between our choosing the recovery target and choosing the LSN to await.
Commit b26f7fa6ae2b4e5d64525b3d5bc66a0ddccd9e24 fixed one case of this.
Fix two more.  Back-patch to 9.6, which introduced the affected test.
