[Cleanup] Remove workaround that only intercepts Pusher + UrbanAirship updates and only applies correct form of reportActions data

[roryabraham]

HOLD on:

• [HOLD for payment 2023-02-02] Intercept Pusher + UrbanAirship notifications and only apply sequenceNumber-keyed updates #14452
• https://github.com/Expensify/Expensify/issues/254606

Problem

In #14452 we will be adding a temporary workaround to gracefully migrate reportActions Onyx data.

Solution

Remove this temporary workaround and go back to the client "blindly" applying Onyx updates it receives from the server.
