Do not process batches if skip file detected in restore_helper

Do not process batches if skip file detected in restore_helper.

When performing restore with resize, batches are used for each table. If the
error happens during restore, there is no need to continue with remaining
batches for this particular table. To signal about an error to the helpers,
main process created skip files.

This patch adds skip of the remaining batches in restore helper when skip file
is detected.

How about to restore loop over batches (as it was before)?

Before that commit there were different lists of oids and batches, so loop in the loop looked natural. Now there is combined oidWithBatchList and IMHO one loop is looking much more relevant.

Removing oidWithBatchList would bring significant changes into the code and unrelated to the current issue tests. The code will not be smaller or more clean since replicated tables should be processed as well.
The problem with extra create/close of pipes can be achieved with much easier way.
