Test files should now ignore has_wal_read_bug() so long as wait_for_catchup() is their only known way of reaching the bug. That's at least five files today, a number expected to grow over time. This commit removes skip logic from three. By doing so, systems having the bug regain the ability to catch other kinds of defects via those three tests. The other two, 002_databases.pl and 031_recovery_conflict.pl, have been unprotected. Back-patch to v15, where done_testing() first became our standard.
