Fix regression: Entities not moving

Commit 53d725f78a, intended to fix an
overzealous commit, was itself overzealous. This is because it applied
to all entities when it should only apply to entity-emitting entities.
To fix this, `entityclonefix` needs to no-op if the entity is not an
entity emitter.

Fixes #1176.
