Remove orders/totals request from notifications manager

[ealeksandrov]

Follow-up to: #7735

Description

This PR updates PushNotificationsManager to prevent triggering data reload notifications on each "app badge clear" action. Without it order list will trigger orders/totals requests on each viewWillAppear.

Same change was already implemented in https://github.com/woocommerce/woocommerce-ios/pull/7459, but Application Icon badge handling accidentally removed with it, so this PR now decouples one from another.

Note: Application icon badge != Orders tab badge. They have different logic and values (app icon can only be 1 or nil)

Testing instructions

1. Allow notifications to display a badge on app icon
2. Place an order to trigger app icon badge update (always "1" for any number of orders)
3. Go to the orders tab and confirm that application badge is cleared, but orders/totals API request is not triggered.

Hey @ealeksandrov, thanks for tackling the https://github.com/woocommerce/woocommerce-ios/pull/7735 fix and adjusting the solution to avoid the problem again! Much appreciated, and sorry for introducing that bug 😅. Just one question to acquire some additional context: I noticed this PR hanging while I was AFK. Is the code here OK for review, or it's waiting for something?

@ThomazFB no worries, I'm pretty sure it's not a final performance improvement that we'll find! PR is ready for review, it wasn't urgent to prioritize earlier and you should have the best context awareness around it 🙂
