fix: init store only once when no web-components

[aralroca]

Fixes https://github.com/brisa-build/brisa/issues/644

Adding an id fixes multi-executions of the same script during SPA, solving the store updates. This bug only happened in a page without any web component, with only the RPC code for the server actions.
