watch_credits: Fix shadowed `controls` variable

Silly me, the `controls` module was getting shadowed by the `controls`
variable in `init_mutation_observer()`, which contained the DOM element.

That's why the controls weren't getting hidden.

Now that we're no longer shadowing the variable, the controls do get
properly hidden.
