high accuracy mode shouldn't turn on while inside zone

## Steps to reproduce

1. enable background location
2. enable high accuracy when entering zone
3. set high accuracy mode trigger range for zone to something > 0 (say, 300m)
4. enter selected zone

## Expected behavior

When I am far away from the selected zone, high accuracy should be off. When I get within 300m of the zone, high accuracy should turn on. After I have entered the zone, it should turn off.

## Actual behavior

High accuracy stayed on after I have entered. Sometimes, it even turns itself on when I am inside the zone.
