Fix bug #2482254: a giant spore exploding was having the mgrd where it used to

be set to NON_MONSTER twice, the second time after the royal jelly had responded to the explosion and spat out a new jelly on the spot the spore used to occupy, leading to the new jelly becoming detached from the mgrd.

Allowing the royal jelly to be radnomly generated in the arena with the random_uniques tag, since it's no longer causing a crash.
