7ac281c19cd3d11f316dbbb3308eabf1ad4f26d6 qa: Add missing coverage of corrupt indexes (Hodlinator)

Pull request description:

  - Add synchronization in 3 places where if the Transaction Index happens to be slow, we get rare test failures when querying it for transactions (one such case experienced on Windows, prompting investigation).
  - Remove unnecessary TxIndex initialization in some tests.
  - Add some test coverage where TxIndex aspect could be tested in feature_init.py.

qa: Wait for txindex to avoid race condition
Can be verified to be necessary through adding std::this_thread::sleep_for(0.5s) at the beginning of TxIndex::CustomAppend.

qa: Remove unnecessary -txindex args
(Parent commit ensured indexes in feature_init.py are actually used, otherwise they would be removed here as well).
