fix: comment test_clear_old_data_too_many_heights

[Longarithm]

Put correct path to this test in nayduck... and comment this test for now, because it doesn't work with resharding data and MockEpochManager. cc #10634

Later, we either should remove resharding scenario or make add_block scenario respect epoch manager.

Later, we either should remove resharding scenario or make add_block scenario respect epoch manager.

Resharding scenario doesn't really exist here as the clear_resharding_data function only does something significant when the shard layout changes.

I think the main issue here is just MockEpochManager :(

[Longarithm]

Oh well maybe the issue is obvious - this amazing assumption of MockEpochManager::get_epoch_and_valset called sequentially for all blocks on chain as comment above it says.
I'm not going to fix it here, anyway.
