Note that this likely didn't work in the first place. deck_beat_watchdog_timer is a free variable, not a member of midi_for_light. It was probably never noticed being part of the rarely invoked shutdown handler.

The error can be reproduced by selecting the MIDI for light mapping and then switching to another mapping (which errors)
The `[-1, -1]` value is likely taken from other scripts where the variable actually holds an array of timers. This is not the case here, so to prevent confusion, we shouldn't use an array where we intend to assign a timer.

This is a first attempt at fixing #13114.
Maybe someone more familiar with the legacy controller scripting system can comment on this, the timer handling in the script did not look sound, so I tried to ensure that timers are only stopped if they are running and that they are unassigned properly if stopped.
