Pending drafts local notifications

Not sure there is a real issue, but since I will not be able to look into it soon-ish, creating this so it's not lost 😄

Don't think it's urgent so adding it to GK project for now.

Expected behavior

The following is what I understood the feature should look like (so my interpretation of it 😄 )

In Notifications settings, the Notify me on pending drafts flag should deactivate/activate local AlarmManager notifications reminding the user about drafts they created on the app but they didn't promote to Published.

Actual behavior

With that flag on or off I did not get local notifications

Steps to reproduce the behavior

The relevant code is in PendingDraftsNotificationsUtils and NotificationsPendingDraftsReceiver. I reduced on purpose the NotificationsPendingDraftsReceiver.ONE_DAY variable to 60 * 1000 so to accelerate the tests. For completeness I'm not even sure we are using that Notify me on pending drafts anymore (but better to confirm it).

• Create a draft post and save it
• You can check the alarms are scheduled using this adb shell dumpsys alarm | grep -i "org.wordpress.android"
• Wait for the first alarm trigger (60 seconds in my accelerated test)
• Notification was not triggered for me

Tested on [OnePlus 7T], Android [10], WPAndroid [16.9 develop]

Start with PendingDraftsNotificationsUtils and NotificationsPendingDraftsReceiver, then reproduce the issue with a saved draft and the accelerated ONE_DAY value. Use adb shell dumpsys alarm | grep -i "org.wordpress.android" to verify scheduling; done means the Notify me on pending drafts setting correctly controls the alarm and a local notification appears after it triggers.
