Stop tracking unwanted trips in fleet mode on iOS

[catarial]

Unwanted trips where there is no BLE beacon are happening on iPhone when using a fleet server. This is caused by not checking for fleet mode when receiving a VISIT_ENDED transition.

This can be tested by using an opcode for a fleet server then forcing a transition into VISIT_ENDED. In the unpatched code this triggers a trip start.

Log showing trip start:

In TripDiaryStateMachine, received transition T_VISIT_ENDED in state STATE_WAITING_FOR_TRIP_START
DEBUG: In TripDiaryStateMachine, received transition T_VISIT_ENDED in state STATE_WAITING_FOR_TRIP_START
data has 96 bytes, str has size 96
data has 69 bytes, str has size 69
started fine location tracking with accuracy = -1 and distanceFilter = 1
DEBUG: started fine location tracking with accuracy = -1 and distanceFilter = 1
In TripDiaryStateMachine, received transition T_TRIP_STARTED in state STATE_WAITING_FOR_TRIP_START
DEBUG: In TripDiaryStateMachine, received transition T_TRIP_STARTED in state STATE_WAITING_FOR_TRIP_START
data has 98 bytes, str has size 98
data has 69 bytes, str has size 69
Moved from STATE_WAITING_FOR_TRIP_START to STATE_ONGOING_TRIP

This was fixed by simply ignoring a VISIT_ENDED transition for fleet mode.

Log after patch, trip doesn't start:

DEBUG: In TripDiaryStateMachine, received transition T_VISIT_ENDED in state STATE_WAITING_FOR_TRIP_START
data has 97 bytes, str has size 97

LGTM! Can you also change the NSLog messages related to fleet transitions to the LocalNotificationHandler logs so that we can see them on real phones and real trips?

[catarial]

Changes to fleet logs compiled and ran. I couldn't verify if it shows in the actual phone log but it shows in the Xcode log.

Got transition T_VISIT_ENDED in state STATE_WAITING_FOR_TRIP_START with fleet mode, ignoring, no beacon found
DEBUG: Got transition T_VISIT_ENDED in state STATE_WAITING_FOR_TRIP_START with fleet mode, ignoring, no beacon found

LGTM!
