[CHORE] refactor: Remove runloop usage in integration tests for store/ find All module

[dmuneras]

Description

• Remove usage of runloop in store - findAll module tests.
• Remove beforeEach loop usage in the module and setup data in each test.

Overall this is good but I don't think we should introduce the "escape the microtask queue" trick for tests that don't need it.

e.g. this

await new Promise(resolve => setTimeout(resolve, 1));

lets refactor these to just return resolve( ...payload... ) vs the async/await with the timeout
