[Spells] Immolate currently treated as a curse

[romgenie]

Revision:
'OregonCore Rev: 3967 Hash: 71a6c59 (Unix,little-endian)'

Operating system:
Linux - Ubuntu 16.04

Current behavior:
As a warlock, after casting Immolate, then casting any curse it will overwrite Immolate.

Expected behavior:
After casting Immolate, then casting any curse it should not overwrite Immolate.

Steps to reproduce the problem:
Cast Immolate on any creature, then cast any curse on a creature and Immolate will be overwritten.

Are you sure it's treated as a curse? Try and remove it on an other character with remove curse.
The fact that it doesn't stack with curses doesn't necessarily mean it's treated as one.

On 3602 rev. all ok. I did: Immolate+CoA; Imm+CoE; and reverse.
