Implement the missing functions `xTimerGetExpiryTime()` and `xTimerIsActive()` for the move of `TimerController` to use FreeRTOS timers. In the process also fix a slight inaccuracy in the ms to ticks conversion (no conversion was done as 1000 was close enough to 1024 for a first working implementation).
