Description

Fixes #2296

This fixes that Keg was not making a sparkle sound when activated when rejoining the server.

Reproducing

Join server, light a Keg, leave and rejoin. Keg isn't making a sound. After this PR, it will make a sound.

For testing, I suggest that you increase the explosion timer in Keg.as
this.set_f32("keg_time", 180.0f); --> this.set_f32("keg_time", 1800.0f);
