Fixed [2.1.18] Rock Spawner rocks not despawning from slopes

[Chromatian]

Rocks spawned from a rock spawner upon entering a sloped sector do not despawn when exiting the sloped sector onto a flat sector:

Raising the sloped sector or lowering the flat sector low enough to cause a bounce allows the rocks to despawn:

I've made a fix for this bug on GitLab: http://git.magicalgirl.moe/STJr/SRB2/merge_requests/162

This happened to me when i was making Mount Torval map for SUGOI 2.

My fix has been merged to next as of now, so this should be fixed for the next patch or release of SRB2.
