Remove `titlemapinaction` check from LD 413 Change Music

This fixes #88 where clients who join mid-level will be triggered by this exec, even when it's not supposed to be global.

Effectively, this reverts the "local/global" check back to what it was in 2.1.

However, this may break use of LD 413 in titlemaps. The more proper solution would be to figure out why titlemapinaction remains true when exiting the title screen. But for a quick 2.2.1 fix, the current bug is more important to mitigate.
