Fix possible 01506_buffer_table_alter_block_structure_2 flakiness
...
SELECT from Buffer table is racy, so you can get data from the
underlying table but not from the Buffer itself, since in parallel with
SELECT, Buffer, can flush it's data to the underlying table.
It is hard to avoid with the current architecture, since this will
require to holding lock until the data will be read from the Buffer, and
this is not a good alternative.
So let's fix the test instead, but not relying on background flush (TTL
increased).
Here is an example of a test failure [1]:
