Improve restart handler

[cpignedoli]

There are cases where it is clear from the CP2K output (ABORT) that the input file is wrong and attempting to restart a failed calculation is useless. We should detect these cases and avoid restarting.

On the other hand, it could happen that restarting cp2k fails because the writing of a .wfn did not complete, in that case, it would be convenient to have the handler point to the latest available .wfn.bak file
