IndexOutOfBounds when rerouting

[LukasPaczos]

Refs #2477.

When re-routing, the previous bearing's list might've been empty which will lead to the IndexOutOfBoundsException. We should fill it with nulls to match the number of coordinates instead.

The reroute request still fails when the initial bearing list was empty (doesn't throw an exception anymore though), the number of new bearing arguments doesn't match.

mapbox-navigation-android/libnavigation-core/src/main/java/com/mapbox/navigation/core/MapboxNavigation.kt

Lines 504 to 515 in c325d9d

	val bearings = mutableListOf<List<Double>>()
	val originTolerance = routeOptions.bearingsList()?.getOrNull(0)?.getOrNull(1)
	?: DEFAULT_REROUTE_BEARING_TOLERANCE
	val currentAngle = location.bearing.toDouble()
	bearings.add(listOf(currentAngle, originTolerance))
	bearings.addAll(
	routeOptions.bearingsList()?.subList(index + 1, coordinates.size) ?: emptyList()
	)
	optionsBuilder.bearingsList(bearings)

Above, the number of bearing arguments should always be equal to the number of coordinates, we need to pass trailing nulls in this case.
