removed random log

i see. well if you are replacing the whole crontab, than you would have to drop existing crons (duno how exactly crontab works, but google is our friend)
and adding crons like should work (again google is friend):
`join(PHP_EOL, $this->getRaw())`
ofc you would have to try
my point is, that doing unnecessary I/Os and creating mess in `/tmp` dir is messy
