Paweł Dziepak f991a2deb5 tests/row_cache_alloc_stress: use another memtable for underlying storage ...

It is incorrect to update row_cache with a memtable that is also its
underlying storage. The reason for that is that after memtable is merged
into row_cache they share lsa region. Then when there is a cache miss
it asks underlying storage for data. This will result with memtable
reader running under row_cache allocation section. Since memtable reader
also uses allocation section the result is an assertion fault since
allocation sections from the same lsa region cannot be nested.
