Make computedFn Warnings Optional?

Getting tons of the warning "invoking a computedFn from outside an reactive context won't be memoized, unless keepAlive is set" due to calling methods that use computedFns inside tests.

Ex: Test calls something like:

` handleSelection = (id) => {
        this.isSelected(id) ? this.deselect(id) : this.select(id);
 };`

to set up test case. And because isSelected is a computedFn, there's a warning for each time it's invoked. I see how these warnings are useful, but would it be possible to make them optional for cases like this?

Start by locating the computedFn implementation and the warning text, then inspect existing tests that invoke computedFns outside a reactive context. Determine how an optional warning setting should be exposed and verify that the default warning behavior remains unchanged while callers can suppress it.
