Broodmother's Spiderling's Poison Sting uses the creep duration against creep-heroes.

Spell durations generally use the hero duration on creep-heroes. Poison Sting should not be an exception to this.

This is especially an issue for Lone Druid. The poison disables the bear's Return ability for 9 seconds when attacked once by a Spiderling.

Repro:
1. Attack a Spirit Bear with a Spiderling
2. Check how long the Poison Sting debuff lasts

Result: It lasts 6 seconds, using the creep duration.

Expected: It should last 2 seconds, using the hero duration.
