Until now, emulation models were always being registered via probe(), which causes the emulator to initialize all the channels. To reduce the overhead, the channels were not connected or registered in the bay until the first event of that model was received. This delayed connect was causing issues in muxes where the newly connected model required refreshing the touched channels. Which in turn was causing unexpected PRV events. By determining which models we need to enable, we can remove the delayed connect mechanism and just enable those models at initialization time, and connect the channels.
