Server does not switch users' dimensional voice channel on death

[griffin4cats]

Unfortunately I'm currently unable to test more thoroughly, but from what I observed, when players died in the nether and respawned in the overworld, they were not switched to the overworld dimension voice channel until they exit the overworld and enter the overworld again.

Versions of mumblelink on all clients were downloaded today, so that should be the most recent version, 0.7.5, on all connecting clients. Nothing was using optifine or any mods that I would assume would interfere with this, aside from maybe lithium on the server.

Tomorrow I should be able to provide whatever information is needed to investigate this more fully.
