[TASK] Separate restore from delete in DataHandler

The DataHandler delete related methods still handle
too many things.
This is yet another divide & conquer patch: Move
the 'undelete' functionality to dedicated methods,
drop handling from 'delete' methods and refactor
'undelete'.
The result is a quite straight forward 'undelete'
implementation, plus reduced complexity in 'delete'.
