Creates empty log file even if there is nothing to report

[Dragonisser]

Not that it really matters since they are empty, but why create a log file if there is no content (except for one time).

This is a relic of me not wanting to deal with opening a file on every log. I should really just rewrite it at some point. PRs welcome though, it'd probably be a better idea to have a static variable that determines if we have an open log file or not
