Explanation: The boned fish's revive ability added a timer that would
randomly fire in the next one-to-two minutes. Due to this inherent
randomness, create-and-destroy would locate the fact that we were
hanging refs to this fish since the timer may not have processed by the
time the fish was deleted (probably if the timer was considerably more
than one minute), so in order to fix this let's just add the
`TIMER_DELETE_ME` flag to the revive ability so that the timer get's
`qdel`'d on the fish's `Destroy()`. simple

i probably cocked up some detail of the above explanation but the timer
flag was literally created to prevent stuff like this from happening so
let's use it
