Fix Performance Optimizer speed controls in SP (#380)

Fixes speed change using hotkeys if speed controls are hidden/disabled while playing in SP. The current patch unconditionally called the MP speed controls, despite not being in MP.

On top of that, this will prevent the mod time control hotkey method from running in MP, which was pointless as (in best case) it would almost immediately return or (in worst case scenario, if MP just handled time change) it would try running the time change code without a reason as it wouldn't be able to do anything anyway.
