Targets report 0/0 for some users after interval turnover

[kennsippell]

Describe the bug
I'm struggling a bit to pin this down to a specific repro, but I think the evidence below indicates quite strongly a problem in handleIntervalTurnover.

To Reproduce
November target document

• All targets report a value of 0
• This target doc has 121 revs, so presumably it wasn't 0 all month. Trying to verify via audit log but stuck.
• If I login as this user in production and set the date to November, I see 95 household visits and 14 referrals in the targets tab. I can also see these values in the target doc during the month of November.
• Last write is Dec 2 midnight EAT (interval turnover on Dec 2)

Nov 30th telemetry indicates:

• User loaded the targets tab successfully!
• No feedback documents reported Nov 30th +/- many days
• They are running CHT Core 4.13
• No reports completed or contacts created. They seem to just login and sync (which is what they are told to do by Nairobi coordinators to ensure end-of-month reporting)

Dec 2nd telemtry

• No activity on Dec 1.
• They load the targets tab like 10 times
• They completed about 32 reports on this single day
• Same DeviceID as Nov 30th telemetry

Expected behavior
Target doc should not report values with all zeros when target tab is showing valid sums

Environment

• Instance: nairobi.echis.go.ke
• App: webapp
• Version: 4.13.0

Additional context
About 7% of eCHIS Nairobi users are reporting that the values on their Nov target documents are incorrect during the first week of December. They are running the fix for #9431. This is causing users to continue to not trust the performance data presented by the eCHIS digital payment system.
