"This Week" staking overview resets stake numbers for days of the previous month at the beginning of a new month

[mossboss007]

Bug Description:
"This Week" staking overview resets stake numbers for days of the previous month at the beginning of a new month
for example on Friday October 1st, when you looked at the "this week" staking summary list Monday - Thursday all reset to 0.000x42, they were all September dates. the October dates of that week show the stake amounts.

Steps to reproduce the bug:

1. wait to the first day of the month then go to "Staking Overview" - "This Week"
2. hit the expander to see all the "This week" stakes
3. if the fist day of the new month is a Friday, the previous days from the prior month Monday - Thursday will all reset to 0.0000x42
4. the stake for Friday and Saturday will show because they are in the current month
5. The total balance shown in the "This Week: " header is also wrong. (only showing the balance of the current month dates.)

Screenshots:
(balances blurred for anonymity) This screen shot was taken on Oct 2nd. you can see there are balances showing for Oct 1st and Oct2 but not for any of the previous September dates.

Expected Behavior:
when there are both dates of the pervious month and the current month in the "this week" summary because of the start of a new month all the days should still show the proper balance. balances for dates in the previous month should not be reset to 0.000
