fix: global emotes not loading (#5435)

* fix: manually initialize twitchircserver after rest of singletons are initialized

this fixes global emotes not being loaded on startup, since initialize
was never called (since it was no longer added to the singleton list)

* unrelated nit: remove copy/move ctors/operators of twitchircserver
