Fix sacrificed Imp click-cast

[lkshrk]

What does this PR do?

Fixes click-cast bindings for a Warlock sacrificed Imp. The generated macro now casts Command Demon, which resolves to the sacrificed Imp Singe Magic action, instead of looking up the overridden spell name directly.

How was it tested?

• Ran wow-check ~/EllesmereUI/EllesmereUIRaidFrames (0 errors).
• Tested on live with Grimoire of Sacrifice and a sacrificed Imp; confirmed Singe Magic click-casts correctly.
• Confirmed wow-errors --match Ellesmere is clean after reload (session 423).
