Update triggering logic for hybrid notification

Currently in the worst case a user can receive 4 battery
notifications if the time estimates and percentages line up right.
This CL makes it so a user can at MOST receive one "low" battery
warning and one "critical" battery warning per charge cycle. A
charge cycle is restarted when a user charges to at least 45%
battery AND has 6 hours remaining. This does not affect the
behavior of the non-hybrid notification.
