When an re-org happens wait_for_blocks(2) would actually exit after the second import of blocks 1, so the conditions for the metric to exist won't be met hence the occasional test failure.

Fix that by adding a new methods which wait for blocks to be finalised, this should guarantee us that the preconditions for running the test are met.

More details in:
#7267
