---Undo changes made to generation of run name. Original idea was to
automatically pass preamble to restarted run. This is not ideal however,
since you may just want to restart a run previously analyzed without
automatically analyzing it. The only solution in this case is to assume
no analysis and require user to explcitly initiate a preamble string. To
do this, delete preamble symbol from run to be restarted by default.
  Now, when restarting a run which has been analyzed before, need to
  specify analysis again: preamble:"scalasca -analyze"
