Fix race condition in recovery/t/009_twophase.pl test. Since reducing pg_ctl's reaction time in commit c61559ec3, some slower buildfarm members have shown erratic failures in this test. The reason turns out to be that the test assumes synchronous replication (because it does not provide any lag time for a commit to replicate before shutting down the servers), but it had only enabled sync rep in one direction. The observed symptoms correspond to failure to replicate the last committed transaction in the other direction, which can be expected to happen if the shutdown command is issued soon enough and we are providing no synchronous-commit guarantees.
Fix that, and add a bit more paranoid state checking at the bottom of the script.
