* Fixes registersignal(s) sound manager runtime (#71667)
## About The Pull Request
RegisterSignal no longer takes lists, so these needed to be updated
The element passed an empty list to the component (caused a runtime but
not one you'd expect) and also registered a list to SSdcs incorrectly
Very cool
