Add extra check and warning on missing player data. 

* For some unexplained reason, `mcl_burning.storage[player]` can
  sometimes be `nil`, causing a crash in `on_leaveplayer()`.  This
  commit adds a check for that.  If a `nil` is encountered, a sane
  value is substituted and a warning is set to the log.
