Throws an error if the new request uses strict handling and there is a change set containing
a strict handling request except the one at index <code>iChangeSetNo</code>. On the other
hand, in case of the "odata.continue-on-error" preference, every request using strict
handling must belong to its own change set.

@param {object} oRequest
  The new request or <code>null</code> to re-check all change sets as a preparation for the
  "odata.continue-on-error" preference
@param {object[]} aRequests
  The batch queue
@param {number} [iChangeSetNo]
  The index of the irrelevant change set; ignored for a <code>null</code> request
@throws {Error}
  If there is a conflicting change set
