Notes

This fixes a console complaint I started to notice today:

Failure populating year in review report: Error Domain=NSCocoaErrorDomain Code=133020 "Could not merge changes." UserInfo={conflictList=(
    "NSMergeConflict (0x6000017d5140) for NSManagedObject (0x60000212cb40) with objectID '0x9c481419d6f2b090 <x-coredata://020B8A47-5DE5-4220-A266-679DB4FEA54B/CDYearInReviewSlide/p1>' with oldVersion = 1 and newVersion = 2 and old object snapshot = {\n    data = \"<null>\";\n    display = 0;\n    evaluated = 0;\n    id = readCount;\n    report = \"0x9c481419d6f2b0a0 <x-coredata://020B8A47-5DE5-4220-A266-679DB4FEA54B/CDYearInReviewReport/p1>\";\n    year = 2024;\n} and new cached row = {\n    data = {length = 1, bytes = 0x30};\n    display = 0;\n    evaluated = 1;\n    id = readCount;\n    report = \"0x9c481419d6f2b0a0 <x-coredata://020B8A47-5DE5-4220-A266-679DB4FEA54B/CDYearInReviewReport/p1>\";\n    year = 2024;\n}"
), NSExceptionOmitCallstacks=true} [WMFAppViewController+Extensions#L626]

I think this is caused by my additional call to populate YiR report data after the user logs in (added in #5074). When an app launches, it makes the populateYearInReviewReport method call twice fairly quickly: Once from performTasksThatShouldOccurAfterBecomeActiveAndResume after the app finishes its launch setup code, and again from userWasLoggedIn. I think something about this is causing merge conflicts on Core Data (the initial report without editing data attempts to save at the same time as the next report with editing data).

To get around this, I am only calling populateYearInReviewReport within userWasLoggedIn if the app has already completed its setup.

Test Steps

1. Ensure you are logged into app for a user with edits from the past year. Delete app, then run again from this branch.
2. Ensure Year in Review entry point appears. Ensure console error does not display.
