Update detection for web components doesn't detect change if previous value was undefined

[alexdor]

I am interested in helping provide a fix!

Yes

Which generators are impacted?

• [ ] All
• [ ] Angular
• [ ] HTML
• [ ] Qwik
• [ ] React
• [ ] React-Native
• [ ] Solid
• [ ] Stencil
• [ ] Svelte
• [ ] Vue
• [X] Web components

Reproduction case

coulnd't make one because it needs a page to render the component as well

Expected Behaviour

The onUpdate method of the web component to be called every time a value from the dependency array changes.

Actual Behaviour

If the previous value of the on update is undefined, then the value of the __hasChanged is undefined and the onUpdate doesn't run.

Additional Information

I've spotted the issue and have solve it locally by replacing the .find calls in packages/core/src/generators/html.ts with .some calls
