Merge #14456: test: forward timeouts properly in send_blocks_and_test

Summary:
94e21c1501 test: forward timeouts properly in send_blocks_and_test (James O'Beirne)

Pull request description:

  Small change motivated by frustrations while writing `feature_block` tests; when a timeout is passed to `send_blocks_and_test` it isn't forwarded onto constituent waiting calls - you can end up waiting 60 seconds when you articulated e.g. 5. Respect the given timeout all the way down.
