Fix cutting of omni_listtransactions
Fix cutting of omni_listtransactions

Previously, when trying to skip transactions of omni_listtransactions, the list wasn't cut, e.g. with this command, when there were only 4 transactions in total:

  omni_listtransactions "*" 10 2

This commit reintroduces proper cutting of the result.
