MS926 Upload count fixes

[luhmirin-s]

Fixed two different issues that messed up up-sync event count reporting:

• We counted all events for the max value, which included the events from open sessions and caused the total to be slightly inflated. One simple join removes this issue - now we only count the events that are actually going to be uploaded.
• Events in the last uploaded scope were counted twice due to "COMPLETE" state carrying the count from the last "RUNNING" state in the up sync task, this caused the progress count to overshoot the "max" (sometimes by significant amounts):
