Summary:
Fixes multiple VCS plugin beginRetrival()/endRetrival()/itemVersion() calls on single directory update.
When VCS pluging finished gathering directory information VersionControlObserver::slotThreadFinished() calls KFileItemModel::setData() on each entry with appropriate item VCS information.
This in turn emits KFileItemModel::itemsChanged() which is connected with VersionControlObserver::delayedDirectoryVerification() which is starting to gather VCS directory information again.
This commits breaks the vicious circle.
