> Transactions over some cells may be recovered after the stale data read.
> For example:
> We have 2 cells, the first contains partitions for k1, second for k2.
> Tx with put(k1,v1) and put(k2,v2) started and prepared.
> Then node from the first cell, which is the primary for k1, failed.
> Currently, the second cell (with key2) may finish the cellular switch before
> tx recovered and stale data read is possible.
> Primaries from the {{tx.transactionNodes()}} should be taken into account
> instead of the current logic that awaits for all transactions located on
> nodes who are backups to the failed primary.
